Flame Retardant Silicone Rubber Parts High Temperature Sealing Gasket New Energy Vehicle Battery Charging OEM

Application Scenarios

These flame-retardant silicone rubber parts are specially developed for the new energy industry, including EV battery pack sealing gaskets, battery management system (BMS) protective pads, charging pile waterproof seals, high-voltage connector grommets, and photovoltaic junction box seals. With UL94 V-0 flame retardancy and stable electrical insulation, they effectively prevent flame spread, moisture ingress, and vibration damage in high-voltage environments, ensuring long-term safe operation of electric vehicles and charging infrastructure.

Simple Parameter Table

Quality Assurance

Quality is built into every stage of our new energy part production. Raw silicone compounds are verified with flame retardancy and dielectric tests before batch release. Key inspection points include Shore A hardness, tensile and tear strength, dimensional measurement with 2.5D projectors, and 100% visual inspection for flash, sink marks, and contamination. Each production lot can be traced through batch records, and we gladly arrange third-party testing to meet your EV industry quality requirements.

Packaging Specifications

Parts are individually protected with anti-static PE bags and separated by EPE foam layers to avoid deformation during transport, then packed in strong 5-layer export cartons with moisture-proof film lining. For high-value or fragile profiles, we offer vacuum packaging or customized trays. Labels with part number, quantity, and date code are applied, and packaging can be adapted to your assembly line requirements such as small-box kanban packing.

After-Sales Service

Our after-sales team provides a 12-month quality warranty against manufacturing defects. Should any issue arise, our engineers will respond within 24 hours, support failure analysis with photos and returned samples, and offer free replacement or remanufacturing. We also assist with material selection advice, sealing structure optimization, and installation guidance for your new energy projects.

Factory Scale

As a manufacturer specializing in silicone rubber and other elastomer parts for 15+ years, we operate a 12,000-square-meter factory with 50+ compression molding machines, 8 injection molding machines, and 4 LSR lines, reaching 5 million pieces monthly capacity. An in-house precision mold workshop and 25+ R&D engineers allow us to complete tooling in 10-20 days and support IATF 16949-style quality management for automotive and new energy clients.

FAQ

Q1: Can you provide the UL94 V-0 test report?
Yes, we can provide test reports from our materials and arrange third-party certification as required.

Q2: Do you support IATF 16949 quality requirements?
Our factory follows IATF 16949 management standards and can complete PPAP documentation with you on request.

Q3: What hardness range is suitable for battery sealing?
For compression seals we usually recommend Shore A 50-70; for cushioning and anti-vibration parts Shore A 30-50 is common.

Q4: What is the tooling lead time for EV parts?
Prototype molds take 7-10 days and production molds 15-25 days depending on complexity.

Q5: Do you keep the drawings confidential?
Absolutely. All customer drawings and designs are protected by strict confidentiality agreements.
