Thermoplastic Polyurethane ( TPU )

Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. Further, it can be processed on extrusion as well as injection, blow and compression molding equipment. Thermopalstic polyurethane ( TPU ) is a unique category of plastic created when a polyaddition reaction occurs between a diisocyanate and one or more diols that results in high resilience, good compression set, plus resistance to impacts, abrasions, tears, weather, and even hydrocarbons. TPU offers flexibility without the use of plasticizers as well as a broad range of hardness and high elasticity. In fact, TPU bridges the material gap between rubbers and plastics.

Other Common Variations:

TPU have some common performance traits that set them apart

from other plastic materials. These typically include:

►High abrasion resistance

►Excellent low-temperature and impact strength

►Resilience to oils, greases and numerous solvents

►Good flexibility over a wide temperature range.

►Robust weather and high-energy radiation resistance.

►Suitability for bonding and welding.

Carboxylated Nitrile ( XNBR )

XNBR Carboxylated Nitrile ( XNBR ) Cabboxylated Nitrile is similar to Nitrile rubber, but the polymer backbone has been chemically modified with Carboxylic Acid containing group. This result is XNBR with more excellent abrasion and tear resistance than traditional NBR. For this reason, XNBR based parts are usually applied in dynamic assembly such as seals and rod wipers. Cure system - Sulfur - Cured Standard XNBR compounds are sulfur-cured Performs Well In… ►Aliphatic hydrocarbon ►Vegetable and mineral oils and greases ►Diesel ►Water Dilute acids, alkali and salt solutions Doesn't Perform Well ...

Silicone Rubber ( MQ, VMQ, PVMQ )

VMQ Silicone Rubber ( MQ, VMQ, PVMQ ) Physically, silicones are based on silicon, an element derived from quartz. To create this class of synthetic elastomers, pendant organic groups such as methyl, phenyl and vinyl are attached to silicon atoms. The different addition of side chains can achieve significant variations in properties. Silicones have excellent heat, ozone and corona resistance, very well dielectric stability, and resistance to many oils, chemicals, and solvents. And for all elastomers, silicones possess the best flexible property ...
