Features
Advanced Cold Shrink Technology
Neither fire operation or special tools nor multiple tubes is required. With its own property of elasticity and excellent radial pressure, encircle cable and shrink in place by simply pulling the plastic core. Our product’s well-fitting ensures a good performance of waterproofing and moisture-proofing.
Excellent Material Performance
Application of imported liquid silicone rubber provides quality insulation and elasticity properties. Our products are capable of maintaining long-lasting radial pressure after installed in cables. Being a top liquid silicone rubber consumer and importer in China, we strive to maintain the consistency and stability of our products.
