Elastomers are unique materials that combine the properties of rubber and plastics, offering flexibility, durability, and resilience. These materials are essential in various industries, from automotive to consumer goods, and they play a crucial role in our everyday lives. But what exactly are elastomers, and what makes them so special?

What are elastomers?

Elastomers, commonly referred to as TPEs (Thermoplastic Elastomers), bridge the gap between thermoset rubber and thermoplastics. They are primarily composed of hard, crystalline segments and soft, rubber-like segments. The hard segments influence properties like heat resistance, oil and solvent resistance, tear strength, and tensile strength. On the other hand, the soft segments impact compression set, low-temperature performance, and impact resistance.

The ratio of hard and soft segments in elastomers drives their hardness, modulus, and flexibility. This unique combination of properties makes elastomers incredibly versatile and suitable for a wide range of applications.

Types of elastomers and their applications

• Thermoplastic Polyolefin (TPO): TPO is known for its low cost, wide range of flexibility, and good weathering resistance. It's commonly used in automotive parts like bumpers and interior trims, providing durability and cost-effectiveness.
• Thermoplastic Styrenic (TPS): TPS offers low density, good compression set, and excellent flexibility at low temperatures. These properties make TPS ideal for shoe soles and other footwear components, ensuring comfort and performance.
• Thermoplastic Vulcanizate (TPV): TPV combines the best properties of rubber and plastics, offering a wide operating temperature window and good oil resistance. It's widely used in automotive, providing very good abrasion resistance, high tear, puncture, and tensile strength, good flexibility at low temperatures and excellent long-term aging stability.
• Thermoplastic Polyurethane (TPU): TPU is known for its high tear, puncture, and tensile strength. It's used in sports equipment like running shoes and protective gear, ensuring durability and performance.
• Thermoplastic Co-polyester (TPC): TPC offers excellent flex fatigue resistance and good hydrolysis resistance. These properties make TPC suitable for aerospace applications, where materials need to withstand extreme conditions.

Why are elastomers important?

Elastomers are essential because they provide solutions to many of the challenges faced by various industries. Their unique combination of properties allows for the creation of products that are durable, flexible, and resistant to various environmental factors. Whether it's in the automotive industry, sports equipment, or consumer electronics, elastomers play a vital role in enhancing the performance and longevity of products.
