Key Features
Common Types
Production & Customization
We support full customization based on:
Core advantage
Stable performance from -60°C to 250°C, resistant to high and low temperatures without deformation or cracking.
Food-grade and medical-grade available, compliant with FDA, LFGB, RoHS certifications; odorless, non-polluting, safe for direct food and skin contact.
High resilience, low compression set, tear-resistant; maintains shape after long-term bending and pressing.
Resistant to ozone, UV, moisture and mildew; long service life, far better than ordinary rubber and plastics.
Soft and fit well, with strong waterproof, dustproof and shock absorption effects.
High insulation performance, stable in different environments, widely used in electronic products.
Flexible hardness (Shore 20–80), customizable colors and shapes; suitable for precision small parts and complex structures.
Smooth, non-stick surface, easy to clean and disinfect; not easy to breed bacteria.

Notes (Recommendations)
Avoid long-term contact with sharp objects, solvents, oils, acids, alkalis, and corrosive chemicals to prevent swelling, deformation, or aging.
Do not use beyond the rated temperature range (-60°C to 250°C). Long-term overheating may cause hardening, cracking, or performance degradation.
Store in a cool, dry, ventilated environment. Avoid direct sunlight, UV radiation, high temperature, and high humidity to extend service life.
Install smoothly without forced stretching, twisting, or extrusion. Ensure proper fitting to avoid damage from improper assembly.
Clean with neutral detergent or clean water. Do not use abrasive brushes or strong chemical cleaners that may damage the surface.
Regularly inspect for wear, hardening, cracking, or loss of elasticity. Replace damaged parts in time to ensure sealing and safety performance.
Select the appropriate grade (food-grade, medical-grade, high-temperature grade) according to the working environment to meet safety and performance requirements.
