About Shenzhen Hongye Siliocn Rubber Co. - Silicone Supplier in China

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.

Product Range and Specialties of Shenzhen Hongye Siliocn Rubber Co.

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.

Trade and Export Information - Shenzhen Hongye Siliocn Rubber Co.

China is a major exporter of silicone rubber, with the majority of shipments classified under HS chapter 40 (rubber and articles thereof). Export volumes are directed toward automotive tire manufacturers, medical device makers, electronics encapsulation firms, and consumer‑goods producers in Europe, North America and Southeast Asia. Importers commonly require ISO 9001 quality management, REACH compliance, and where applicable RoHS or FDA certifications, especially for medical or food‑related applications. Shipments are typically packed in 200 L steel drums or bulk‑bag containers, loaded in 20‑foot or 40‑foot containers, and traded on FOB Shanghai or CIF Europe terms.

Logistical handling of silicone rubber demands temperature‑controlled storage to prevent premature cure, and customs authorities often request the HS code 4002.19 (other polymerised rubber) together with a certificate of origin and a conformity declaration. Chinese exporters frequently provide pre‑shipment inspection reports (e.g., SGS, Bureau Veritas) to satisfy buyer due‑diligence in high‑value markets such as the EU automotive sector or U.S. medical device industry.

Sourcing from Shenzhen Hongye Siliocn Rubber Co. - Buyer Guidance

When sourcing silicone molding compounds from Shenzhen Hongye Siliocn Rubber Co., request a full technical data sheet that lists viscosity (cSt), Shore A hardness range, cure schedule (temperature and time) and any filler content. Ask for recent third‑party test reports covering ASTM D412 tensile strength, ASTM D2240 hardness and DIN 53130 compression set to verify that the material meets your application tolerances. Verify that the supplier can provide REACH registration numbers and, if required, FDA or USP compliance certificates before confirming an order.

Typical minimum order quantities for silicone rubber compounds range from 500 kg to 1 ton, depending on the grade and packaging format. Lead times for bulk production in China are usually 30 - 45 days from receipt of a confirmed purchase order and approved sample. Ensure that packaging meets your logistics plan - drums for liquids, sealed bulk bags for solid compounds - and confirm the Incoterm (FOB or CIF) that aligns with your import strategy.

What silicone products does Shenzhen Hongye Siliocn Rubber Co. list?

The supplier lists five silicone products: liquid silicone rubber for gypsum molds, a general‑purpose platinum‑cured silicone rubber, a platinum‑cured silicone rubber for tire molds, silicone rubber for general mold making, and pad‑printing silicone rubber.

Are there any certifications listed for these silicone rubbers?

The facts do not specify any certifications held by the supplier. Buyers should request REACH registration, ISO 9001 quality management and, where relevant, FDA or USP compliance certificates as part of the sourcing process.

What technical specifications should I request for these silicone rubbers?

Request viscosity (cSt), Shore A hardness range, cure temperature and time, tensile strength (ASTM D412) and compression set (DIN 53130). A material safety data sheet (MSDS) and a technical data sheet (TDS) are standard documents for verification.

What are the typical packaging options for silicone molding compounds?

In the industry, liquid silicone is commonly shipped in 200 L steel drums, while solid or paste‑type silicone is packed in bulk bags (up to 1 ton) or sealed cartons. Confirm the packaging size that matches your handling and storage capabilities.

Which markets typically import silicone rubber from China?

Major import markets include automotive tire manufacturers in Europe, medical device producers in North America, electronics encapsulation firms in Southeast Asia, and consumer‑goods companies worldwide.

What HS code is used for silicone rubber exports from China?

Silicone rubber compounds are generally classified under HS chapter 40, often using code 4002.19 for other polymerised rubber products. The exact sub‑code depends on the specific formulation and physical state.

What are common payment and shipping terms for Chinese silicone rubber suppliers?

Buyers usually negotiate FOB Shanghai or CIF Europe terms. Payment methods often involve a letter of credit or a T/T advance against a pre‑shipment inspection report.

What is the typical lead time for an order of silicone rubber from this supplier?

Lead times are typically 30 to 45 days from order confirmation, assuming the required specifications and certifications have been approved and raw material availability is stable.
