lohkopolymeerit

Lohkopolymeerit, also known as thermoplastic elastomers, are a class of polymers that combine the properties of both thermoplastics and elastomers. They are characterized by their ability to be repeatedly softened by heat and hardened by cooling, similar to thermoplastics, but also exhibit elastic properties similar to elastomers. This unique combination allows lohkopolymeerit to be processed using techniques similar to thermoplastics, such as injection molding, extrusion, and thermoforming, while also providing the flexibility and resilience of elastomers.

Lohkopolymeerit are typically composed of two distinct phases: a soft, elastomeric phase and a hard, crystalline or amorphous phase. The elastomeric phase provides the material with its flexibility and resilience, while the hard phase contributes to its strength and stiffness. The balance between these two phases can be adjusted to tailor the properties of the material to specific applications.

Lohkopolymeerit are used in a wide range of applications, including automotive parts, seals, gaskets, hoses, and cables. They are valued for their ability to withstand repeated flexing and compression, as well as their resistance to chemicals, oils, and other harsh environments. Some common examples of lohkopolymeerit include styrene-butadiene-styrene (SBS), thermoplastic polyurethane (TPU), and thermoplastic vulcanizates (TPVs).
