Guangdong Times Energy Storage New Materials Technology Co., Ltd. / Dongguan Times Silicon Industry Co., Ltd.
Battery systems are unforgiving on materials. A battery pack has to absorb vibration on rough roads, hold up as a protective barrier in a thermal event, insulate high-voltage harnesses, and keep its sealing and thermal performance for years — all at once.
Liquid silicone rubber (LSR) answers all four demands. And compared with commodity rubbers and foamed plastics, it does so across a temperature span of -50℃ to 200℃, with stable compression set, strong electrical insulation and certified flame retardancy.
Not many Chinese LSR manufacturers can serve this industry at scale. Times Silicone — operating as Guangdong Times Energy Storage New Materials Technology Co., Ltd. and Dongguan Times Silicon Industry Co., Ltd. — is one of them. Founded in 2023 in Dongguan, Guangdong, the company is a high-tech enterprise focused on liquid silicone rubber and silicone oil, supplying customers in new energy vehicles, battery energy storage, rail transit and communications electronics.
1. Where LSR Works Inside a Battery System
Open up a battery pack and you will find LSR almost everywhere: cushioning pads between cells, protective foam between modules and the enclosure, thermally conductive structural parts, insulation for cables and connectors, seals, gaskets and potting compounds.
The hard part for a manufacturer is not making silicone — it is making it consistent. New energy customers run long validation cycles and hold every batch to tight tolerances. One drifting batch can drag down yield across an entire production line. Consistency is exactly where our R&D effort goes.
2. Foamed LSR: The Foam Structure Decides the Quality
Take our TE-JC040 series (TE-JC040-G01A / G01B, 1:1 two-part mix), developed for battery module cushioning and rail transit protection. The numbers speak for themselves:
Closed-cell ratio ≥ 95%, with fine, uniform cell walls and 30% more specific surface area than conventional foam. Weight gain below 1% after 72 hours in water at room temperature — the hydrophobic protection does not fade. Batch-to-batch expansion ratio spread of just 0.3, with a wide processing window and low sensitivity to temperature and pressure. Operating range -50℃ to 200℃, flame retardant to UL94 V-0 at 1.5 mm.
In plain terms: the foam cures evenly, stays dry, and comes out the same every batch. For module builders running high-volume orders, these three points are what stand between a smooth line and constant rework.
3. Ceramifiable LSR: A Fire Barrier That Outlasts the Flame
Energy storage stations and EV makers keep raising the bar on thermal runaway protection. Ceramifiable LSR handles this differently from ordinary flame-retardant rubber: under direct flame it sinters into a hard ceramic-like layer that keeps its shape and insulation after the fire passes — buying critical protection time for battery packs and cable runs. This is one of the product directions new energy and storage customers ask about most.
4. Bonding, Composite and Solid Grades — Built Around Your Line
Beyond foam and ceramifiable grades, the product range covers bonding-grade silicone, composite silicone, solid silicone and silicone primers. The bonding system adheres directly to metal and plastic substrates in-mold, cutting out primer steps. Solid grades span multiple hardness levels for seals, cushions, thermally conductive parts and overmolding, and process well by injection, coating or potting.
Every grade can be tuned to your application and process conditions. That is what new energy customers value most in a supplier: not selling a pail of rubber, but working with you until the material passes validation and runs at volume.
