The global liquid silicone rubber (LSR) market, valued between USD 2.8 billion and USD 3.8 billion in 2024, is projected to reach USD 5.0–7.55 billion by 2030–2035, driven by demand for high‑purity, durable elastomers in industries from healthcare to renewable energy. As manufacturers seek materials that combine thermal stability, chemical resistance, and regulatory compliance, LSR has become a cornerstone of advanced product design. Dongguan Times Silicon Industry Co., Ltd. positions itself as a reliable partner in this landscape, offering a portfolio of platinum‑cured LSR solutions backed by rigorous certifications and scalable production.

Problem & Opportunity

Traditional thermoset elastomers often fall short in extreme environments where temperature swings, voltage stress, or biocompatibility are critical. Silicone‑based materials, particularly liquid silicone rubber, bridge this gap with a unique combination of properties: a service temperature range from −60°C to +200°C, inherent flame retardance, and resistance to ozone, chemicals, and moisture. For engineers designing EV battery packs, photovoltaic modules, or medical devices, selecting a material that meets both performance and regulatory demands is paramount. The opportunity lies in LSR’s ability to simplify assembly (overmolding, injection molding) while delivering consistent, repeatable quality across high‑volume production runs.

Brand Solution

Dongguan Times Silicon Industry Co., Ltd., founded in 2021 and operating since July 2022, specializes in the R&D, production, and sales of new silicone materials. Its 15,000 m² facility houses a dedicated R&D team of 10 engineers and an annual production capacity of 5,200 units. The company’s core LSR products include Adult Products LSR for Overmolding (hardness 7±1 to 38±1 Shore A, clear appearance), Formed Liquid Foamed Silicone Rubber (hardness 17–51, tear strength 15–17), Vinyl Silicone Oil (viscosity 35–50 W, vinyl content 0.037–1.497), and Platinum Catalysts (platinum content 1,000–5,000 ppm). All formulations are addition‑curing (platinum‑cured) for low volatility and high purity. The company has passed ISO 9001 certification, and every product carries RoHS, REACH, FDA, LFGB, and halogen‑free certifications, making them suitable for food contact, medical, and high‑risk electrical applications. With export sales accounting for 55% of total revenue and markets spanning China, South Korea, the United States, Japan, and Africa, Times Silicon provides globally compliant LSR solutions.

Technical Explanation

The addition‑curing (platinum‑catalyzed) system used in Times Silicon’s LSR products relies on hydrosilylation between vinyl‑terminated polydimethylsiloxane and hydrogen‑containing polysiloxane. The platinum catalyst (models TPL‑1000 to TPL‑5000, PTR‑3000 to PTR‑5000) enables rapid, controlled crosslinking with no by‑products, resulting in a transparent, low‑volatility elastomer. Viscosities range from 320 mPa·s (catalyst) to 350,000 mPa·s (foamed rubber), and hardness from ultra‑soft 7 Shore A to firm 51 Shore A. The absence of peroxide decomposition products makes platinum‑cured LSR inherently safe for medical and food‑contact applications. Mechanical parameters such as tensile strength (5–7 MPa), elongation at break (300–500%), and tear strength (15–17 kN/m) for the foamed grade demonstrate robust physical performance.

Application & Use‑Case Scenarios

Electrical Insulation in New Energy Vehicles
The Fiber Glass Sleeve with Silicone Resin (models TS3034B, TS3039B, TS3045‑01B, TS3045B, TS3049B, TS6123A/B, TS6125A/B) is applied by dipping, spraying, or brushing onto fiberglass sleeves, then high‑temperature baked to form a dense insulating coating. It withstands 200°C continuously, meets UL94 V‑0 flame retardancy, and resists oil mist, dust, and acid/alkali corrosion. This coating is used in motor windings, transformer insulation, and EV wire harness protection across markets including the US, Vietnam, Japan, and South Korea.

Overmolding for Consumer & Adult Products
The Adult Products LSR for Overmolding (TS6807A/B to TS6838A/B) bonds directly to plastic and hardware substrates, delivering a soft‑touch, high‑resilience surface that is odorless, anti‑yellowing, and non‑toxic. Common in the US, Vietnam, and Thailand, it meets food/medical grade requirements and provides exacting tactile realism for toys and daily necessities.

New Energy Battery R&D & Chemical Synthesis
The Platinum Catalyst (TPL and PTR series) catalyzes hydrosilylation in silicone product manufacturing, PU foam production, and new energy battery R&D. It operates across a wide temperature range (−20°C to +150°C) and is suitable for solvent‑free or organic solvent systems, with high activity and low toxicity.

Market Trend Analysis

Several data points underscore the strategic importance of LSR. Medical‑grade LSR alone generated approximately USD 458.7 million in 2024, and the thermally conductive silicone rubber market is expanding at a CAGR of 8.3% through 2034, fueled by high‑power density in EV batteries and 5G hardware. Notably, about 63% of EV battery pack sealing systems now rely on silicone elastomers. These trends align with Times Silicon’s focus on new energy applications: its 2023 subsidiary, Guangdong Times Energy Storage New Material Technology Co., Ltd., concentrates exclusively on silicones for EVs, rail transit, and renewable energy storage.

Comparison with Traditional Solutions

Compared to traditional thermoset rubbers (e.g., EPDM, polyurethane) or thermoplastics, platinum‑cured LSR offers superior thermal stability (−60°C to +200°C), lower compression set, higher purity (no peroxide residues), and compliance with medical/food standards without compounding complexity. One honest limitation is that LSR tooling costs are typically higher, and processing requires precise control of temperature and catalyst activity, making it less economical for very small‑scale runs or extremely high‑volume commodity parts where cheaper materials suffice. Nevertheless, for applications demanding performance, certification, and repeatability, LSR remains a cost‑effective choice through reduced scrap rates and longer service life.

Future Outlook

With global LSR demand accelerating in electrification, medical devices, and 5G infrastructure, suppliers that offer certified, customized formulations will gain competitive advantage. Times Silicon’s dual‑structure – a parent company covering full‑category LSR and a dedicated subsidiary for new energy silicones – positions it to serve both broad industrial needs and specialized high‑growth segments. As regulations tighten around volatility, flame retardancy, and environmental footprint, its compliance‑first approach (ISO 9001, RoHS, REACH, FDA, LFGB, halogen‑free) provides a ready foundation for OEMs and brand owners.
