Conclusion：
Excellent oil resistance: It can effectively resist the erosion of isooctane and 903 grease. When in contact with oily substances, it maintains stable physical and chemical properties, does not cause swelling, deformation, performance degradation and other problems, and ensures the long-term reliability of the product in the oil environment.
Processing performance: It has good compatibility with EVA resin, is easy to disperse evenly during processing, is suitable for molding and injection foaming processes, and is convenient for producing foam products of various shapes and specifications.
Oil resistance: After the test piece is immersed in isooctane oil for 24 hours, the volume expansion coefficient does not exceed 6%. The international standard is that it is qualified within 12%.
Applicable in other molded foam products where oil exposure is a concern, offering extended product life and reduced maintenance.
Application Scenarios:
This masterbatch is specifically engineered for use in applications that require both foaming and oil resistance.
Typical use cases include:
Shoe Soles for Industrial and Workplace Settings
Ideal for manufacturing oil-resistant soles for:
Kitchen footwear (anti-slip and oil-repellent)
Mining boots (durable and impact-absorbing)
Gas station and factory shoes (resistant to fuel and grease exposure)
Usage method:
Mix ratio: According to the durability and physical performance requirements of the specific foamed sole and the production process, mix the oil-resistant foaming masterbatch with the basic EVA resin in an appropriate ratio.

Dongguan Yiyuan Polymer Materials Co., Ltd. is a company that integrates R&D, production, processing, sales of polymer plastic elastomer materials, plastic modified raw materials, plastic products, and sales of other chemical products (excluding hazardous chemicals): import and export of goods or technology (except for goods and technology import and export prohibited by the state or involving administrative approval).
The company is deeply engaged in professional fields, customer-oriented, and is committed to the modification and solution provision of rubber and plastic raw materials. It advocates reducing the burden on the earth and promoting the recycling of environmentally friendly new materials. Yiyuan provides customers with raw material application technology services, including raw material testing, formula design, product testing, and solving problems in the raw material application process.
Since its establishment, it has invested in the construction of a technical research and development system and established a testing and analysis laboratory. It has independently developed functional materials such as high-elastic particles, lightweight high-elastic particles, ethylene elastomers, thermoplastic elastomers, spot removers, wear resistant agents, shock-absorbing masterbatches, shrinkage stoppers, GRS certified materials, and bio-based certified materials.
Wear-resistant agent is a kind of polymer material made by blending EVA as carrier, silicone coupling agent as main component and active agent. It can reduce the wear of rubber and plastic materials. It will not affect the light resistance, weather resistance, ozone resistance and other physical properties of rubber and plastic materials. Wear-resistant agent is most suitable for TPR, PCU (PVC physical foaming), EVA foaming and other foaming materials.
