Descripción de los productos
Coace ® W1G-F is an anhydride modified Styrene-Ethylene-Butylene-Styreneelastomer with good stability and aging resistance.
Designed to give great aging resistance and improved interfacial adhesion between organic polymers and inorganic fillers or reinforcements, the Anhydride Modified S-EB-S Elastomer is a complex polymer. Including anhydride groups into the S-EB-S structure generates reactive sites that can create covalent connections with inorganic materials, therefore enhancing the general stability and performance of composite materials.
Designed especially to increase the compatibility and interfacial bonding between organic polymers and inorganic materials, the aging resistance macromolecular coupling agent is a novel polymeric addition. Advanced macromolecular architectures help this coupling agent not only increase the mechanical and thermal characteristics of composite materials but also extend their service life.

Some uses of grafted SEBS are as follows:
- High anti-aging performance: By means of acid anhydride modification, the material’s thermal stability and oxidative stability are much enhanced, so enabling its maintenance of good physical characteristics in high temperature conditions.
- Enhanced Weathering Resistance: The product is made to withstand degradation from UV radiation, moisture, and temperature variations, therefore extending the life of the composite material.
- Chemical Stability: The coupling agent is fit for uses in demanding surroundings since it shows great resistance to many different chemical agents.
- Improved Mechanical Strength: Tensile strength, modulus, and abrasion resistance of the composite are much improved by coupling agent optimization of the dispersion of inorganic fillers.
- After the maleic anhydride grafted SEBS was added, the Tg of PC in the blend PC/PBT shifted to low temperature, and the Tg difference between the two was further reduced, which improved the compatibility of the blend.
- Thermal Insulation Properties: The product helps the composite to be thermally insulated, therefore lowering heat transfer and preserving the integrity of the material under high temperature.
Ventaja
The aging resistance of the coupling agent guarantees that the composite material preserves its characteristics over a long period, therefore lowering the demand for regular replacements.
Wide range of inorganic materials, including fillers, reinforcements, and coatings, makes the coupling agent a flexible solution for many different sectors.
Improving the performance and lifetime of composite materials helps the coupling agent present a reasonably cheap substitute for conventional materials and additives.
Environmental Sustainability: Through lower environmental impact of material deterioration and disposal, the product helps to generate sustainable materials.
Excellent anti-aging function of the product helps to considerably extend the service life by preventing cracking, discolouration, and other issues during long-term usage.
Lower maintenance expenses: Excellent mechanical qualities and longevity help to lower material replacement frequency, so lowering total maintenance costs.
broad spectrum of uses: relevant to several sectors, including consumer goods, medical, and automotive, satisfying various fields for high-performance elastometers.
Anhydride modification technology simplifies processing of the material, and many complicated forms of goods can be tailored depending on consumer requirement.
