LSR Liquid Silicone Rubber is a high-precision, fast-curing material engineered for injection molding and high-volume industrial applications demanding consistency and efficiency.
Powered by platinum-catalyzed chemistry, it offers ultra-low viscosity (3,500-5,000 cp) for easy flow into complex mold cavities and rapid vulcanization (≤30 seconds at 180°C), enabling mass production of intricate components with minimal downtime. Compliant with ISO 10993 for medical biocompatibility and UL 94 V-0 for flame resistance, it excels in automotive, electronics, and healthcare industries where performance, safety, and production speed are critical.

High-Speed Processing: Cures 10x faster than conventional rubber materials (e.g., EPDM, natural rubber), reducing molding cycle times from minutes to seconds. This boosts production throughput by up to 300% in high-volume settings, lowering per-unit costs for mass-produced components .
Chemical Resistance: Withstands degradation from automotive oils, industrial solvents, coolants, and UV radiation, ensuring longevity in harsh operating environments. Its resistance to swelling and hardening extends component lifespan in under-the-hood automotive applications and outdoor electronics.
Biocompatibility: Complies with USP Class VI and ISO 10993-5 standards, making it safe for medical devices such as catheters, breast pump components, and implantable accessories. It supports multiple sterilization methods (autoclave, gamma irradiation, EtO) without performance loss.
Design Flexibility: Low viscosity enables molding of micro-features (e.g., 0.1mm flow channels, thin walls down to 0.2mm) and seamless overmolding onto plastics (PP, PC, ABS) and metals, creating multi-material components with enhanced functionality.
Automotive Industry: Produces gaskets, seals, and airbag components with excellent compression set resistance (≤5% after 22 hours at 200°C), ensuring reliability in engine and chassis systems.
Electronics: Used for LED encapsulants (light transmittance ≥85%), connector boots (moisture resistance IP68), and sensor diaphragms, providing superior dielectric stability for high-voltage applications.
Healthcare: Ideal for syringe plungers (smooth glide performance), wearable device seals, and orthotic liners, meeting strict sterilization and biocompatibility requirements.
Consumer Goods: Creates baby bottle nipples (BPA-free, soft-touch), smartwatch straps (sweat-resistant), and kitchen appliance gaskets, combining durability with user-friendly tactile properties.
Our LSR undergoes ISO 17025-accredited testing for viscosity consistency (±5% tolerance), cure kinetics (real-time monitoring via rheometry), and aging resistance (10,000-hour thermal stability tests). Each shipment includes a Process Validation Report and UL File Number E345678 for flame resistance verification. Digital batch tracking ensures full traceability from raw material receipt to final delivery.
