Products Description
Coace® W1G-2 is an anhydride modified Styrene-Ethylene-Butylene-Styrene elastomer with good stability and aging resistance. It is used as impact modifiers for polyamides and their composites, including PA6, PA66, and PA/FR.”
Polyamide compounds, often known as nylons, are widely utilized in a variety of sectors due to their high mechanical qualities, thermal stability, and resistance to wear and chemicals. However, these materials can be fragile, particularly at lower temperatures, and are prone to environmental aging, which can reduce their performance over time. To solve these issues, the use of aging-resistant impact modifiers has become critical.
The use of anhydride-modified SEBS elastomers as impact modifiers in polyamide compounds marks a significant achievement in material engineering. These elastomers improve polyamides’ mechanical characteristics, thermal stability, and aging resistance, allowing them to be used in a variety of demanding applications across several industries. SEBS-modified polyamides’ versatility and performance enhancements ensure that they remain a preferred material for producers looking for long-lasting, high-performance solutions.

Chemical Structure: The SEBS backbone is made up of styrene and butadiene blocks, which give a combination of stiffness and flexibility. The anhydride modification introduces reactive groups, which improve adhesion to polar substrates such as polyamide.
Elasticity: SEBS elastomers have rubber-like elasticity, which considerably increases polyamide compounds’ impact resistance, particularly at low temperatures.
Thermal Stability: This elastomer retains its qualities over a wide temperature range, ensuring that the modified polyamide is durable in a variety of environments.
Aging Resistance: The anhydride modification provides resistance to oxidative aging and UV degradation, extending the life of polyamide compounds.
Advantage
Enhanced Impact Resistance: By integrating SEBS elastomer, polyamide compounds gain toughness and reduce brittleness, which is important in applications needing high impact strength.
Improved Flexibility: SEBS elastomers make polyamides more flexible, making them suited for dynamic applications that demand frequent flexing and bending.
Thermal Performance: SEBS’s exceptional thermal stability means that polyamide compounds may survive high processing and operating temperatures without degradation.
Chemical Compatibility: The anhydride groups improve the chemical compatibility of SEBS with polyamides, resulting in greater dispersion and stronger interfacial adhesion in the polymer matrix.
Aging and Weathering Resistance: The SEBS elastomer is very resistant to environmental influences such as UV radiation and oxidative chemicals, allowing polyamide compounds to preserve their mechanical capabilities even after prolonged exposure to harsh environments.
