About Hongkong Hong Ye Jie Technology Co., Ltd. - Synthetic Rubber Supplier in China

China hosts the supplier Hongkong Hong Ye Jie Technology Co., Ltd., which currently lists five distinct silicone rubber products in its catalogue. The catalogue includes Injection silicone rubber, Molding silicone rubber, RTV‑2 silicone rubber, Silicone potting and Addition molding silicone, all classified under the synthetic rubber family. Each product is identified by its functional designation rather than a brand name, and the supplier reports a total active product count of five.

The listed silicone rubber types serve typical applications such as electronic encapsulation, automotive sealing, medical device potting and general industrial molding. The product set reflects the common segmentation of silicone elastomers into injection‑mouldable grades, room‑temperature‑vulcanising (RTV‑2) compounds, potting compounds for circuit protection and addition‑cure moulding grades. The supplier’s catalogue does not provide HS codes, so the products fall under the broader HS chapter 40 for silicones.

Product Range and Specialties of Hongkong Hong Ye Jie Technology Co., Ltd.

The five products cover the principal silicone rubber segments used in B2B sourcing. Injection silicone rubber is supplied in a liquid or paste form suitable for high‑volume injection moulding, typically offering Shore A hardness from 30 to 70 and operating temperatures from - 50 °C to +250 °C. Molding silicone rubber is a high‑tear‑strength compound often formulated to meet FDA 21 CFR 177.2600 for food‑contact applications and is available in durometer ranges of 40‑80 Shore A. RTV‑2 silicone rubber is a two‑component, room‑temperature‑vulcanising system used for sealing and gasketing, commonly tested to ASTM D412 for tensile strength and elongation. Silicone potting compounds are designed for electronic encapsulation, with low viscosity, high dielectric strength (≥ 30 kV/mm) and compliance with IEC 60947. Addition molding silicone is a addition‑cure grade offering low shrinkage and high dimensional stability, often specified by ISO 10135 for silicone elastomers.

Industry practice for these silicone grades includes certification to ISO 9001 quality management, material safety data sheets (MSDS) and compliance with REACH and RoHS directives for hazardous substances. Buyers also look for test reports covering hardness (Shore A), tensile strength (MPa), elongation at break (%) and compression set (%), as well as thermal ageing data for high‑temperature applications.

Trade and Export Information - Hongkong Hong Ye Jie Technology Co., Ltd.

China ranks among the world’s largest exporters of silicone elastomers, with the majority of shipments classified under HS 4002 (Silicones, in primary forms or in preparations). Typical import markets include the United States, Germany, Japan and South‑East Asian manufacturing hubs, where silicone rubber is used in automotive seals, consumer electronics and medical device assemblies. Buyers generally require compliance documentation such as REACH registration, RoHS declarations and, where applicable, UL or IEC certifications for electrical safety. Standard export packaging consists of 200 L drums, bulk bags (1 ton) or insulated cartons, and shipments are frequently quoted on FOB Shanghai or CIF Rotterdam terms.

Logistics for silicone rubber from China often involve 20‑foot containers that can hold up to 18 metric tonnes of bulk material, with temperature‑controlled containers used for grades sensitive to premature cure. Exporters from coastal ports such as Shanghai, Shenzhen and Qingdao follow Chinese customs procedures that include product classification under HS chapter 40, inspection for hazardous substance limits, and issuance of a certificate of origin for preferential tariff treatment under various trade agreements.

Sourcing from Hongkong Hong Ye Jie Technology Co., Ltd. - Buyer Guidance

When sourcing silicone rubber from this supplier, buyers should request a current technical data sheet (TDS) that details hardness, tensile strength, elongation, operating temperature range and recommended cure schedules. In addition, a material safety data sheet (MSDS) and any available third‑party test reports (e.g., ASTM D412, IEC 60947) should be obtained before confirming a purchase. Verifying REACH registration numbers and RoHS compliance statements helps ensure regulatory acceptance in EU and North American markets.

Typical minimum order quantities for bulk silicone elastomers range from 500 kg to 1 ton per grade, with lead times of four to six weeks after order confirmation, depending on the specific formulation and packaging. Buyers should specify packaging preferences (drum, bulk bag, or insulated container) and confirm the Incoterm (FOB, CIF or DAP) to align with their logistics chain. Sample quantities of 500 g to 1 kg are common for laboratory evaluation of cure behavior and mechanical properties.

What silicone rubber grades are listed in the catalogue?

The catalogue lists Injection silicone rubber, Molding silicone rubber, RTV‑2 silicone rubber, Silicone potting and Addition molding silicone, each representing a distinct processing method and application sector.

Are material safety data sheets available for these products?

Buyers should request the latest MSDS from the supplier; MSDS are standard documentation for silicone elastomers and cover handling, storage and hazard information.

Which industry standards are typically applied to silicone rubber?

Common standards include ASTM D412 for tensile testing, ISO 10135 for silicone elastomer specifications, IEC 60947 for electrical insulation and FDA 21 CFR 177.2600 for food‑contact grades.

What certifications are usually required for importing silicone rubber?

Importers generally ask for ISO 9001 quality management certification, REACH registration, RoHS compliance and, where electrical use is intended, UL or IEC certification.

What are the typical packaging options for bulk silicone rubber?

Standard export packaging includes 200 L steel drums, 1‑ton bulk bags and insulated cartons; packaging choice depends on the grade’s sensitivity to moisture and temperature.

What is a common minimum order quantity for these silicone products?

Bulk orders commonly start at 500 kg per grade, though the supplier may accommodate smaller sample quantities of 500 g to 1 kg for testing.

How long does it usually take to receive an order after confirmation?

Lead times are typically four to six weeks, varying with product formulation, production scheduling and required packaging.

Which HS code family does silicone rubber fall under?

Silicone elastomers are generally classified under HS chapter 40, specifically HS 4002 for silicones in primary forms or preparations.
