Thermoplastic Polyurethane - TPU

Highest Elongation and softest Shore A 70-83 - In serial production since 2014

The use of TPU has proven itself especially in industrial series production for elastic products. 

For instance, TPU is used to produce seals for windows or cars. 

Grippers and tubes made of TPU are applied in automation. 

Orthopedics also benefit from this material to produce shoe soles or their components. 

Famous Sneaker giants are using since 2016 our TPU for 3D printed prototypes.

The right material increases your profitability!

Many TPU powders have poor flowability and are difficult to process. 

With our ROLASERIT® TPU you are making the right choice as we have significantly improved the flow properties and allow easy processing of TPU. 

In addition, almost no aging effects occur. 

Low refresh rates in the range of the generated part volume, or the repeated processing of the material without refreshing, enable an extremely economical part production.

Processing on all common laser sintering machine possibleIn contrast to other TPU powders, ROLASERIT® TPU is not subject to excessive, disturbing smoke emission and laser decomposition of the material, which would lead to low-molecular decomposition products.

A simple exposure of the cross sections is sufficient to achieve optimum product properties. 

Thus, our TPU can be used on all common laser sintering machines - a clear advantage for companies with limited machinery.

An elongation at break that impresses

Components manufactured from this material show elongations at break partially well over 500 %, with results of over 200 - 300 % even in the z-direction.

In addition, excellent surface properties and high edge sharpness with good detail resolution can finally be achieved.

Lowest Shore hardness on the market

The hardness can be variably adjusted by process settings between 70 and 85 Shore A. 

In comparison, the material has one of the lowest Shore hardnesses on the market. 

All products are immediately ready for use without infiltration, pressure-tight up to 5 bar and can be easily dyed.

ROLASERIT® TPU is available in natural, grey-black and glow in the dark blue/green versions.

Polypropylene – PP

Low material costs are easy on your wallet

Compared to the standard PA12 and PA11, polypropylene stands out in particular due to its excellent chemical resistance at a low density and lower material costs. 

AM POLYMERS has been offering PP in various versions since 2017. 

It is harder and more heat resistant than PE and easy to process on all machines, thus meeting your specific requirements in the best possible way.

PP01 and PP01GR (Powerful yet affordable)

ROLASERIT® PP01 and PP01GR can be used for a wide range of applications, from simple casings, ventilation systems, parts for household appliances or liquid containers to functionally integrated elements. 

ROLASERIT® PP01 is the first PP type commercialized by AM POLYMERS. 

It is characterized by processing properties comparable to PA12 and PA11. 

The material is processable on all machine types. Unlike other PP materials, handling with a blade is unproblematic. 

The costs of this material are significantly lower than the prices of usual standard materials, so that its use offers economic advantages for many component groups but also for prototypes.

Perfect quality

PP01 has a low tendency to curl and warp, making it easy to set up a robust processing. 

Components made of PP01 have good mechanical properties and, in contrast to many other new material developments for powder bed fusion, exhibit ductile part behavior with elongations at break exceeding 30%. 

The fracture behavior corresponds to that of PA12, with the otherwise typical characteristics of PP. 

Young's modulus [N/mm²]:  820

Tensile strength [N/mm²]:     18

Elongation at break in %:  > 30

PP03O and PP03GR (PP in top form)

The newly developed ROLASERIT® PP03O expands the portfolio of powder-bed fusion by a material with outstanding ductility and injection molding properties. 

For the first time, no lower elongation at break must be accepted, as was previously the case in additive manufacturing. 

Most materials only show results in the range below 50 % for the xy-plane. 

With over 200% elongation at break, PP03 plays a pioneering role in the field of materials for laser sintering. 

Results of up to 80 % are also achieved in the building direction. 

PP03 in Bestform

The processing of PP03 is possible on all common laser sintering systems without any problems.

New application possibilities with extended functionality

Compared to PP01, components made of ROLASERIT® PP03O allow an extended use of functionalities such as film hinges. 

The high ductility guarantees that the function is maintained even after numerous cycles. 

PP030Compared to many other PA12 and PP materials for powder bed fusion, this new development is characterized by exceptional impact strength and notched impact strength values. 

Based on its high ductility, this material is excellently suited for series production, so that applications in car interiors are also possible. 

Young's modulus [N/mm²]:   800

Tensile strength [N/mm²]:      21

Elongation at break in %:   > 200

PP04 (Increased requirement profile for particularly high demands)

ROLASERIT® PP04 is currently being developed and is intended to offer a polypropylene with a higher stiffness and strength profile than PP01 and PP03. 

The aim is to better cover the special requirements in the automotive sector. 

AM POLYMERS is constantly working to expand the range of materials in the field of polypropylene. 

Beyond the PP04, several PP modifications are currently being qualified. 

Increased requirement profile for particularly high demands

Young's modulus [N/mm²]: 1300

Tensile strength [N/mm²]:     25

Elongation at break in %:  > 10 

PP05 (The inexpensive alternative for your mass production)

As a particularly cost-saving option, we have developed the PP05 in addition to the PP01. 

With only a slight decrease in the component characteristics and at the same time good processability, we were able to significantly reduce the costs of the powder compared to PP01. 

The material is therefore particularly suitable for the production of prototypes and also enables a reduction in the cost of parts compared to PA12. 

Young's modulus [N/mm²]: 820

Tensile strength [N/mm²]:    18

Elongation at break in %: > 18

Polybutylene terephthalate – PBT

- Joint tailored development with Mitsubishi Chemical Corporation -

PBT01

PBT is used especially for valve parts, plug connectors and electrical/electronic components, but also for pump housings and wheels, household appliance components, headlight housings and automotive components.

Clear advantages over standard materials in powder bed fusion

Compared to PA12 and PA11, PBT has better mechanical properties and much lower moisture absorption, as well as higher heat resistance. 

In a joint development with Mitsubishi Chemical Corporation, AM POLYMERS is currently developing a PBT material which is characterized by good processability and good mechanical component properties comparable to injection molding.

No need for high temperature system

Unlike other PBT powders, no high-temperature equipment is required for processing ROLASERIT® PBT01. 

The material can be processed on all common standard systems for powder bed fusion. 

Hence, this material is available on the market without restrictions.

Ductility that pays off

ROLASERIT® PBT01 has mechanical properties corresponding to typical injection molded PBT materials. 

In addition, it has a high elongation at break of 14 % compared with other available powders, with good layer-to-layer bonding in the direction of building. 

As a result, even finer structures can be produced without the risk of damage when unpacking or blasting.

Also with carbon or glass fibers

Furher, we offer with the PBT01CF and the PBT01GF two filled materials with high modulus (5500 to 6200 MPa) and tensile (up to 60 MPa) having significant higher heat deflection of up to 180 °C.

Young's modulus [N/mm²]:   2750 - 6350

AM POLYMERS is committed to innovation and progress in the plastic powder industry.

That is why we are constantly working on new solutions to meet your increased requirements.

For the first time, a PA66 material for laser sintering or powder bed fusion is introduced.

PA66-01 Development product

Typical applications of PA66 are in the field of mechanically and thermally stressed moulded parts in electrical, mechanical, automotive and apparatus engineering, e.g. coil formers, plain bearings, gear wheels, guide and coupling parts, housing parts.

PA66 is characterised in particular by high heat distortion and ageing resistance, high hardness, rigidity and abrasion resistance.

In classical plastics processing, polyamide 66 is much more important than PA12 and PA11, which are used for special applications. 

Even in dry condition good elongation at break

Even in the dry state, the material has a high elongation at break of 15 % in the building plane.

This means that the material does not become brittle even at high operating temperatures, so that even small features and details in functional components can be realised.

In addition, the material is flame-retardant according to UL94-V2.
