About Hong Kong Hong Yejie Silicone Rubber Co. - Agriculture Supplier in China

China‑based Hong Kong Hong Yejie Silicone Rubber Co. lists five active silicone rubber products in its catalogue. The products cover printing pad silicone rubber, mould‑making RTV silicone rubber, RTV liquid silicone rubber for sculpture moulds, silicone rubber injection mould making, and silicone rubber for building decoration. Each item belongs to the broader silicone rubber family classified under HS chapter 39, commonly recorded in HS codes 3917‑3918 for silicone products in primary or finished form. The supplier’s catalogue focuses on applications in agricultural processing, building finishes and artistic moulding, reflecting the listed top category of Agriculture. The product count of five indicates a narrow but specific product portfolio within the silicone polymer segment.

Product Range and Specialties of Hong Kong Hong Yejie Silicone Rubber Co.

The catalogue includes printing pad silicone rubber, which is typically supplied in sheets or pads with Shore A hardness values between 30 and 50, suitable for ink transfer. Mould‑making RTV silicone rubbers are usually two‑component systems with cure times ranging from 5 to 30 minutes and hardness grades from 10 to 70 Shore A, often identified by the RTV‑2 or RTV‑316 standards. RTV liquid silicone rubber for sculpture moulds is supplied as a liquid that cures to a flexible elastomer, commonly meeting ISO 10147 for silicone elastomers used in casting. Silicone rubber injection mould making material is a high‑viscosity compound designed for injection processes, often characterized by melt flow index values between 2 and 8 g/10 min and tensile strength around 6 - 10 MPa. Silicone rubber for building decoration is generally provided in profiles or sheets with UV‑resistance, typically complying with ASTM C1175 for weatherability. Industry practice also sees these products conforming to ISO 9001 quality management and, where food contact is involved, FDA 21 CFR 177.2520 or EU REACH registrations.

Trade and Export Information - Hong Kong Hong Yejie Silicone Rubber Co.

China is a major exporter of silicone rubber products, with shipments typically destined for Europe, North America and Southeast Asia where automotive, construction and consumer goods manufacturers source elastomers. The HS 39‑family codes used for silicone rubber facilitate customs classification; buyers often request the exact HS code (e.g., 3917 90 for silicone in primary forms) to ensure tariff treatment. Commonly required certifications include ISO 9001 for quality management, REACH registration for chemical safety, and UL or CE marks when the material is used in electrical or building applications. Export shipments are usually packed in bulk drums, wooden crates or cardboard cartons, with moisture barriers to preserve material properties, and are shipped under Incoterms such as FOB Shanghai or CIF Hong Kong. Chinese exporters of silicone rubber also provide material safety data sheets (MSDS) and test reports to comply with importing country regulations.

Sourcing from Hong Kong Hong Yejie Silicone Rubber Co. - Buyer Guidance

When evaluating Hong Kong Hong Yejie Silicone Rubber Co., buyers should request the latest ISO 9001 certificate, REACH registration details and any specific FDA or CE compliance documents relevant to the intended application. Test reports for Shore A hardness, tensile strength, elongation at break and thermal stability (e.g., TG‑DTA up to 250 °C) help verify that the silicone rubber meets industry specifications. Samples of each product type are typically supplied in 1 kg or 5 kg quantities, allowing laboratory assessment of cure time, viscosity and mechanical performance before bulk ordering. Verify packaging integrity, especially for liquid RTV compounds, and confirm that the supplier can meet standard container loads of 20 ft or 40 ft containers, which usually hold 18 - 22 metric tons of silicone rubber material.

What types of silicone rubber products does Hong Kong Hong Yejie list?
