Compounds

ProTex Med™ Implantable Polypropylene (PP)

Aran's homopolymer polypropylene Protex Med™ is a permanently implantable material that is suitable as granulate for injection molding or extrusion processing. It is certified according to ISO 10993-5 (cytotoxicity) and is suitable for long-term implants.

LoPro™ - X-ray contrasting compounds

LoPro® Compounds offer enhanced radiopacity for thin-walled, small-profile medical devices.

Nanomed™ compounds with higher flexural strength

Nanomed® compounds are custom formulated to improve structural performance of medical grade polymers, while minimizing the effect on flexibility, ductility and surface finish.

ProPell™ Low Friction Compounds

ProPell™ Low Friction Compounds incorporate proprietary surface enhancing additives into a wide range of medical grade polymers to reduce inherent coefficient of friction, while retaining desired mechanical properties.

Additives

Bismuth subcarbonate

Particle sizes of less than 0.3 micrometers (1.2 x 10-5 inches) allow optimal dispersion of the X-ray contrasting filler in the polymer during melt mixing. This results in optimal surface finish and uniform X-ray opacity throughout the component.

calc-i-pur™ β tricalcium phosphate (TPC)

A biocompatible mineral powder made from calcium salt and phosphoric acid, which promotes bone growth in orthopedic implants.

Combat™ Antimicrobial Masterbatch

Combat AD for bonding with thermoplastic urethanes (TPU) and silicones for medical devices that linger in the body, such as central venous catheters (CVCs). Combat AK is used in polycarbonate and acrylonitrile butadiene styrene (ABS) polymers for components and devices with touch-intensive surfaces, such as bed rails, diagnostic device housings and instrument handles.

High-performance polymers

Pebax® MED polyether block amide

These thermoplastic elastomers combine soft elastomer and rigid polyamide segments, which enables a wide range of physical and mechanical properties. They are plasticizer-free, melt-processable and certified in accordance with USP Class VI and ISO 10993.

Rilsan® MED Polyamide 11

Rilsan® polymers are flexible polyamides made from castor oil with a specific weight of 1.03, 15% lighter than nylon 6. They offer excellent stretchability, low moisture absorption and replace glass or metal in medical applications.

Rilsan® FKZM 65 0 TD MED

FKZM MED is a highly glass-filled advanced polymer with engineering-grade properties, made from bio-based polyamide 11. It offers excellent physical properties, biocompatibility, steam sterilizability, chemical resistance, processability, a wide color range, and great aesthetics.

Rilsan® Clear MED Polyamide/Copolyamides

Rilsan® Clear grades (G170, G850) are polyamides that combine transparency, low weight and flexibility. More transparent than glass and more flexible than polycarbonate, ideal for respiratory masks and hearing aids.

Rilsamide® MED Polyamide 12

Rilsamid® polymers, flexible polyamides made from hydrocarbons, have the lowest density (1.01) of all polyamides. They offer excellent formability, low moisture absorption and are suitable for extrusion and injection molding.

Kynar® MED PVDF

The thermoplastically processable fluoropolymer Kynar® offers excellent chemical resistance, high purity, thermal stability, low friction, high tensile strength as well as gas and radiation resistance. USP class VI certified, sterilizable via gamma or steam.

Isothane® Thermoplastic Urethanes (TPU)

Aromatic thermoplastic polyurethanes are available in polyether and polyester grades. Continuous production ensures consistency with Shore hardness of 75A to 70D. Some grades have been successfully tested according to USP Class VI.

MX nylon (MXD6)

Semi-crystalline, semi-aromatic polyamide made from meta-xylene diamine offers higher mechanical strength than nylon 6/6, lower moisture absorption and improved gas barrier properties, ideal for packaging.
