The anti-static performance is unstable, posing significant production risks. The resistance value of standard products fluctuates unpredictably, with substantial variations within the same batch, and the effectiveness is compromised when temperature or humidity changes. During production, static electricity cannot be effectively dissipated, increasing the likelihood of damaging precision electronic components, chips, and PCBs, resulting in defective semi-finished products and reduced yield rates.
The anti-static effect lasts only briefly, with rapid degradation and failure occurring over time. Most anti-static solutions employ surface coating rather than permanent internal anti-static properties: after prolonged use subjected to friction, wiping, aging, and environmental oxidation, their anti-static performance gradually diminishes until complete failure. While initially passing inspection, these systems secretly fail later-workshop mounting pads, buffer washers, and cleanroom seals all degenerate into ordinary silicone materials.
The hidden costs are substantial, with significant losses incurred from rework and product scrapping. After electrostatic failure occurs, dust and impurities are adsorbed, contaminating precision products. In mass production, latent defects arise, necessitating subsequent rework, returns, and customer compensation claims, which elevate production costs, increase raw material consumption, and delay delivery schedules.

Advantages of Anti-static silicone sponge rubber
Permanent anti-static properties achieved through body modification rather than surface coating
Sanpu Silicone employs an filling formulation process to uniformly incorporate anti-static functional particles into the foam silicone matrix.
The entire material inherently possesses anti-static properties, achieving genuine permanent anti-static performance that remains effective even under prolonged use, repeated friction, and extreme temperature conditions.
Stable Anti-static Performance:
The product's surface resistance is stably maintained within the range of 10⁶ to 10¹⁰ Ω, with uniform resistance values and minimal batch variation.
Anti static silicone sponge has uniform resistance value, stable batch consistency
Leading in domestic market share, serving high-end major clients
Sanpu silicone, as a anti-static foam silicone gel provider ,ranks first in China in terms of customer base and maintains a leading market share. Its products are consistently supplied to state-owned enterprises, listed companies, and precision electronics manufacturers, having undergone large-scale production validation and rigorous industry standard certifications.
With mature formulations and proven manufacturing processes-unlike makeshift formulas adopted by small workshops-the product's quality has been rigorously tested through long-term mass production by major clients, ensuring reliability, durability, and reliable substitution for both imported and conventional domestic materials.
