Shenzhen Hongye Siliocn Rubber Co.

Based in Shenzhen, China, Shenzhen Hongye Siliocn Rubber Co. currently lists five active products in its catalogue. The company is classified as an imported supplier with a harbor trust tier. Its product portfolio falls under the silicone, raw rubber and synthetic rubber categories. The listed items are all variants of silicone rubber used in molding applications. The catalogue does not include raw or synthetic rubber items despite the broader category tags.

The five silicone products include liquid silicone rubber formulated for gypsum molds, a general‑purpose platinum‑cured silicone rubber, a platinum‑cured silicone specifically designed for tire molds, a silicone rubber for general mold making, and a silicone rubber formulated for pad printing. Each product is identified by its functional application rather than a grade designation. The listings reference standard silicone chemistry but do not provide detailed specifications such as Shore hardness or viscosity. The supplier’s catalogue groups these items under the broader silicone category, reflecting a focus on molding compounds.

The catalogue covers five silicone‑based molding compounds: a liquid silicone for gypsum molds, a standard platinum‑cured silicone, a tire‑mold specific platinum cure, a general mold‑making silicone, and a pad‑printing silicone. In the broader industry, liquid silicone fluids are graded by viscosity (e.g., 10 - 1000 cSt) and purity, while platinum‑cured rubbers are classified by Shore A hardness (typically 20 - 80) and temperature resistance (up to 250 °C). Tire‑mold silicones often require higher tear strength and lower compression set, and pad‑printing silicones are formulated for low viscosity and rapid de‑gassing.

Buyers of silicone molding compounds usually request compliance with ISO 9001 quality management, REACH registration for EU markets, and, where relevant, FDA or USP <661> certification for food‑contact applications. Typical industry standards include ASTM D412 for tensile properties, ASTM D2240 for Shore hardness, and DIN 53130 for compression set. Suppliers often provide material safety data sheets (MSDS), technical data sheets (TDS), and batch‑level test reports to demonstrate conformity with these specifications.
