OEM Liquid Silicone Rubber: Custom High-Performance LSR for New Energy & Medical Applications
OEM Liquid Silicone Rubber: Custom High-Performance LSR for New Energy & Medical Applications
Dongguan Times Silicon Industry Co., Ltd. is a Chinese manufacturer specializing in the R&D, production and sales of new silicone materials, including liquid silicone rubber (LSR). The company offers OEM and ODM production services for LSR formulations tailored to demanding applications in new energy, medical devices, automotive, consumer electronics, and adult products.
Why Custom LSR Manufacturing Matters
As industries push the boundaries of performance, off-the-shelf liquid silicone rubber often falls short. EV battery packs require sealing materials that withstand thermal cycling and high voltage; medical devices demand biocompatibility, low odor, and precise hardness; adult products need realistic touch and durability. A one-size-fits-all approach forces trade-offs in cure speed, adhesion, or regulatory compliance. OEM LSR manufacturing solves this by allowing engineers to specify every parameter—hardness, viscosity, color, odor level, curing method, and packaging—directly from a partner with deep formulation expertise.
Industry Context: LSR Market Growth
The global liquid silicone rubber market was valued at approximately USD 2.8 billion to 3.8 billion in 2024, with expectations to reach USD 5.0 billion to 7.55 billion by 2030–2035 (Grand View Research, GMI, MRFR). Medical-grade LSR generated about USD 458.7 million in 2024 (Grand View Research). In the new energy sector, approximately 63% of EV battery pack sealing systems utilize silicone elastomers for flexibility and durability (Precedence Research / IEA). Thermally conductive silicone rubber, critical for EV batteries and 5G hardware, is projected to grow at a CAGR of 8.3% through 2034 (SNS Insider). These trends underscore the need for a responsive OEM partner that can deliver certified, custom LSR at scale.
Dongguan Times Silicon: OEM/ODM Capabilities
Dongguan Times Silicon provides full OEM and ODM production services. The company’s core capabilities include:
- Customization parameters: Shore hardness (7±1 to 38±1 A), viscosity (4,000–25,000 for overmolding grades), color (transparent, translucent, opaque), odor level (low/odorless), formulation grade (food/medical), curing method (room/heat cure), packaging specifications, and custom skin feel (e.g., soft flesh-like, high resilience).
- Monthly production capacity: 80 tons/month, scalable to 110 tons/month for peak seasons.
- Lead time: 7–10 working days for standard stock products; 15–25 working days for custom formulations or bulk orders (adjustable based on complexity and quantity).
- MOQ: 1 kg for standard products; 5 kg for custom formulations (negotiable for long-term partners).
- Quality control: Raw material incoming test (purity, heavy metals, harmful substances), in-process monitoring (viscosity, hardness, mixing ratio), finished product full test (curing performance, odor, biocompatibility), third-party sampling for FDA/ROHS compliance.
- Certifications: ISO9001:2015 (Quality Management System); all products comply with RoHS, REACH, FDA, LFGB, and halogen-free standards. The company holds a High-tech Enterprise Certificate and a Utility Model Patent for a silicone rubber treatment device.
Step-by-Step OEM Partnership Process
- Requirement analysis: Share target application, desired hardness, curing method, regulatory needs (FDA, USP Class VI, etc.), and volume expectations.
- Formulation development: The in-house R&D team (10 engineers) adjusts the platinum-catalyzed addition-cure system to meet your exact specs. Small laboratory samples (≥1 kg) are produced.
- Sample testing: Customer evaluates cure behavior, mechanical properties, odor, and biocompatibility. Iterations are made until the formulation passes all criteria.
- Pilot run & approval: A pilot batch (5–25 kg) is manufactured under production conditions to confirm consistency and scalability.
- Mass production: Full-scale manufacturing with in-process monitoring and finished product testing. Batches are tracked for traceability.
- Delivery & after-sales support: Products shipped via dedicated chemical courier (DHL, UPS). After-sales includes formulation optimization guidance, 24-hour quick response, defective product return/exchange guarantee, and dedicated account manager.
Proven Use Cases
1. High-Activity Platinum Catalyst for Addition-Cure LSR
A platinum catalyst (Pt content 1,000–5,000 ppm) enabled a large liquid silicone manufacturer to increase curing efficiency by 30% and per-batch capacity by 25%. The formulation is adaptable to low-odor, medical/food-grade silicones with no residual odor. Over a 3-year cooperation, the defect rate dropped from 2.5% to 0.6%, yielding 99.4% product yield. Annual purchase volume: 80 kg (regular 5 kg batches) for the manufacturer; 500 kg annually for a top organosilicon group.
2. Realistic Body Mold & Adult Toy LSR
A platinum-catalyzed overmolding LSR (TS6807A/B–TS6838A/B series) provided adjustable hardness 7–38 Shore A, biocompatibility tested, non-bleeding, non-irritating. Used for male masturbators, vibrators, and eggs. Over 3 years, defect rate fell from 3% to 0.8%, yield reached 98%. Annual purchase from a Chinese brand client: 80 tons (5 tons/batch). End-product service life ≥3 years. Clients in China, US, Germany, UK, France, Japan, South Korea, Thailand, Vietnam.
3. Silicone Resin for Fiberglass Insulation Sleeves
Methylphenyl silicone resin (TS3034B–TS3049B series) forms a dense, flexible coating on glass fiber sleeves for high-voltage electrical protection. Temperature range: -60°C to 200°C. Over a 3-year cooperation with an automotive wire harness factory, coating defect rate reduced from 2.8% to 0.5%, yield increased to 99.5%. Annual purchase: 300 tons (13 tons/batch). Sleeve service life ≥10 years.
