Anti-Static Agent for Silicone Rubber

Product Introduction

This silicone-specific anti-static agent is a high-efficiency ionic/non-ionic composite antistatic modifier customized for silicone materials. It has excellent compatibility with solid silicone, liquid silicone, silicone gel and silicone sealant. When blended evenly into silicone raw materials during mixing, vulcanization or curing, it can form a continuous conductive micro-network inside the silicone matrix, effectively eliminating static accumulation on the silicone surface without damaging the original softness, transparency, high and low temperature resistance and food-grade safety of silicone products. It is a permanent anti-static additive, avoiding the short service life defect of traditional surface-spray antistatic coatings.

Key Features

1. Excellent miscibility with all silicone substrates, no precipitation, blooming or whitening on finished product surfaces
2. Permanent anti-static performance, will not fade after long-term friction, washing or aging
3. Low addition dosage, obvious static elimination effect, surface resistance stably controlled within 10⁶–10⁹ Ω/sq
4. Does not affect silicone vulcanization speed, tensile strength, elongation at break and hardness
5. Good thermal stability, withstands high-temperature vulcanization up to 200–230°C without decomposition
6. Transparent grade available; will not cause yellowing or turbidity of transparent silicone parts
7. Low odor, non-toxic, compliant with mainstream food contact and environmental standards
8. Good oil resistance and weather resistance, suitable for indoor and outdoor silicone products

Core Advantages

1. Permanent static dissipation: Unlike temporary spray antistatic agents that wear off easily, this internal additive maintains stable anti-static performance throughout the product service life
2. Wide compatibility: Works for HTV solid silicone, LSR liquid silicone, silicone foam, silicone adhesive and silicone coating
3. Cost-effective: Low recommended addition ratio (1–5 wt%), greatly reduces production cost compared with full conductive silicone fillers
4. No negative impact on silicone properties: Preserves silicone’s unique flexibility, waterproof, insulation and high-low temperature resistant characteristics
5. Easy processing: Directly mixed with silicone base rubber, matching standard silicone kneader and injection molding production lines without extra process adjustment
6. Environment-friendly: Free of heavy metals, halogen-free, meets RoHS, REACH and FDA food contact requirements
7. Stable surface resistance: Consistent anti-static effect under low humidity environment, no failure in dry climate

Recommended Dosage & Usage

Add 1%–5% of the silicone raw material weight during rubber mixing or liquid silicone stirring. Fully knead for 8–15 minutes to achieve uniform dispersion, then proceed with normal vulcanization, injection or curing procedures. The addition amount can be adjusted according to target surface resistance requirements.
