About Shenzhen Hong Ye Jie Techonology Co., Ltd - Silicone Supplier in China

China, Shenzhen, lists five active silicone rubber products in its catalogue. The items are Liquid Pad Printing Silicone Rubber Material, Medical Grade liquid silicone rubber for shoe in, RTV Liquid Molding Silicone Rubber for Concrete, HY-F663 Foaming Silicone Rubber, and Electronic Potting Silicone Rubber. Each product is a liquid silicone rubber formulation designed for a specific end‑use such as printing pads, medical‑grade footwear components, concrete moulding, foamed seals and electronic encapsulation. The supplier is classified as an imported tier with a harbor trust level, indicating it operates through established import channels. No additional corporate history or financial data is provided.

The five listed products belong to the broader silicone rubber family that is coded under HS chapter 40 for rubber and plastics. Liquid silicone rubbers are supplied as low‑viscosity liquids that cure at ambient or elevated temperatures, and they are differentiated by cure type (RTV, condensation, addition) and functional additives such as foaming agents or fillers. The catalogue shows a focus on specialty applications rather than commodity silicone, covering sectors from printing technology to construction and electronics.

Product Range and Specialties of Shenzhen Hong Ye Jie Techonology Co., Ltd

The catalogue covers liquid silicone rubber formulations for distinct industrial uses. Liquid Pad Printing material typically targets a Shore A hardness of 30‑50 after cure and a viscosity range of 600‑1200 cP, allowing fine detail transfer on flexible substrates. Medical Grade silicone for shoe insoles must comply with FDA 21 CFR 177.2600, usually offering biocompatibility, low extractables and a Shore A of 20‑40. RTV Liquid Molding silicone for concrete is a condensation‑cure system that can achieve tensile strength of 4‑6 MPa and is formulated to resist alkaline environments. HY‑F663 Foaming silicone incorporates a chemical blowing agent, producing a closed‑cell foam with density around 0.3 g/cm³ and compression set below 5 %. Electronic Potting silicone is a low‑viscosity addition‑cure rubber used for encapsulating components, often meeting IEC 60695‑2‑11 fire‑safety standards and providing a Shore A of 60‑80 after cure. Typical industry specifications such as viscosity, Shore hardness, tensile strength and compliance standards are used by buyers to compare similar products.

Trade and Export Information - Shenzhen Hong Ye Jie Techonology Co., Ltd

China is a major exporter of silicone rubber, with shipments recorded under HS 4001‑4002 for uncured rubber compounds. Buyers in North America, Western Europe and Southeast Asia regularly import liquid silicone rubbers for automotive, electronics, medical and construction applications. Commonly required certifications include ISO 9001 quality management, ISO 14001 environmental management, REACH registration for the EU, RoHS compliance for electronic potting, and FDA compliance for medical‑grade grades. Export packaging usually involves 200 L steel drums or 25 kg polypropylene containers, loaded in 20 ft or 40 ft containers with moisture‑proof liners. Incoterms such as FOB Shenzhen or CIF Shanghai are typical for these bulk chemical shipments.

Sourcing from Shenzhen Hong Ye Jie Techonology Co., Ltd - Buyer Guidance

When sourcing liquid silicone rubber from this supplier, buyers should request a full technical data sheet that lists viscosity (cP at 25 °C), Shore A hardness after cure, tensile strength, elongation at break and cure schedule. A material safety data sheet (MSDS) and, for medical or food‑contact grades, evidence of FDA or EU compliance should be obtained before contract. Samples are usually supplied in 1 kg drums; a common minimum order quantity for bulk supply ranges from 500 kg to 1 ton, with lead times of 30‑45 days after order confirmation. Verify that the supplier can provide test reports from an accredited laboratory for the specific grade requested, and confirm packaging details such as drum sealing and container load plan to avoid moisture ingress during transit.

What types of silicone rubber does Shenzhen Hong Ye Jie Techonology Co., Ltd offer?

The company lists five liquid silicone rubber products: a pad‑printing formulation, a medical‑grade rubber for shoe insoles, an RTV molding compound for concrete, a foaming silicone (HY‑F663) and an electronic potting rubber.

Which standards should a buyer check for the medical grade silicone rubber?

Buyers should verify FDA 21 CFR 177.2600 compliance, request biocompatibility test reports, and confirm that the material meets any applicable ISO 10993‑1 cytotoxicity requirements.

What is the typical packaging for bulk silicone rubber shipments?

Bulk silicone rubber is commonly packed in 200 L steel drums or 25 kg polypropylene containers, which are then palletised for loading into 20 ft or 40 ft containers.

Which certifications are usually required for electronic potting silicone?

Electronic potting grades are often required to have REACH registration, RoHS compliance, IEC 60695‑2‑11 fire‑safety certification, and an ISO 9001 quality management system.

What are typical quality parameters buyers request for the foaming silicone (HY‑F663)?

Buyers usually ask for foam density (≈0.30 g/cm³), closed‑cell content (>95 %), compression set (<5 %), and Shore A hardness after cure (60‑80).

What is a common lead time for orders from this supplier?

Lead times are typically 30‑45 days after order confirmation, depending on product volume and required documentation.

How can a buyer verify the material’s viscosity before purchase?

The supplier should provide a viscosity measurement in centipoise (cP) at 25 °C on the technical data sheet; a sample can be tested by the buyer’s lab to confirm the value.

What HS code family applies to these silicone rubber products?

Silicone rubber compounds are classified under HS chapter 40, specifically HS 4001‑4002 for uncured rubber, which covers the liquid silicone materials listed.
