Description

Coace®W1G-2 is an anhydride modified Styrene-Ethylene-Butylene-Styreneelastomer with good stability and aging resistance.

The key features and benefits of Coace®W1G-2 include:

Stability: The anhydride modification improves the stability of the elastomer, making it resistant to degradation when exposed to environmental factors such as heat, oxygen, and UV radiation. This ensures that the material retains its properties over a longer period.

Aging resistance: Coace®W1G-2 exhibits excellent resistance to aging, meaning it can maintain its performance and physical properties even after prolonged use or exposure to harsh conditions. This makes it suitable for applications requiring long-term durability.

Elasticity and flexibility: Like other SEBS elastomers, Coace®W1G-2 possesses exceptional elasticity and flexibility, allowing it to stretch and recover without permanent deformation. This property makes it suitable for applications where resilience and deformation recovery are crucial.

Processability: The thermoplastic nature of SEBS elastomers enables them to be easily processed using conventional thermoplastic techniques such as injection molding, extrusion, and blow molding. This facilitates the manufacturing and customization of products using Coace®W1G-2.

Characterisitic

Coace®W1G-2 is a specific type of elastomer known as an anhydride modified Styrene-Ethylene-Butylene-Styrene (SEBS) elastomer. SEBS elastomers are a class of thermoplastic elastomers (TPEs) that combine the properties of both rubber and plastic. They exhibit excellent elasticity and flexibility like rubber, along with the processability and thermal stability of plastics.

Coace®W1G-2 is specifically formulated with anhydride modification, which refers to the addition of an anhydride functional group to the SEBS polymer structure. This modification enhances the properties of the elastomer, particularly its stability and aging resistance. The anhydride groups can react with other materials or functional groups, allowing for improved cross-linking and increased durability.
