(Other TPE) Other ThermoPlastic Elastomers

Thermoplastic elastomers offer a unique combination of rubber-like elasticity and the processability of thermoplastics, such as:

1. Styrenic block copolymers (SBC):

Structure: These blocks consist of polystyrene blocks alternating with rubbery polymer blocks such as butadiene or isoprene.

Properties: Excellent elasticity, good abrasion resistance, and good processability.

Applications: Shoe soles, toys, automotive parts, adhesives.

2. Thermoplastic polyurethanes (TPU):

Structure: Based on polyurethane polymers.

Properties: High strength, abrasion resistance, and toughness. Excellent resistance to oil and grease.

Applications: Footwear, automotive parts, medical equipment, sports equipment.
3. Thermoplastic polyolefins (TPOs):

Structure: Usually polypropylene (PP) or polyethylene (PE) blended with elastomers such as ethylene-propylene rubber (EPR).

Properties: Impact resistance, flexibility and weatherability.
Applications: Automotive parts (bumpers, fenders), outdoor applications.

4. Copolyester elastomers (COPE):

Structure: Copolymers of polyester and polyether blocks.
Properties: High strength, good chemical resistance and excellent hydrolytic stability.
Applications: Automotive parts, medical equipment, sporting goods.

5. Thermoplastic polyamides (TPA):

Structure: Based on polyamide (nylon) polymers.
Properties: High strength, good abrasion resistance and high melting point.
Applications: Automotive parts, gears, bearings.

6. Silicone elastomers:

Structure: Based on silicone polymers.
Properties: Excellent temperature resistance, flexibility at high and low temperatures, biocompatibility.
Applications: Medical devices, electrical insulators, high temperature applications.
