Product Overview
Our Platinum Cure High Temperature Resistant LSR is a high-performance dual-component addition curing liquid silicone rubber, composed of high-purity flowable Part A (base rubber) and Part B (platinum curing agent). It adopts advanced platinum curing system, which is fundamentally different from ordinary condensation curing silicone mold rubber—similar to how precious metal catalysts outperform copper-based alternatives in industrial processes—ensuring higher purity, better stability, and superior high-temperature resistance. With ultra-pure formula (cyclic content < 300ppm) and excellent thermal stability, it solves the pain point of ordinary Mold Making Silicone with poor high-temperature resistance, easy aging, and toxic residues. It achieves shrink-free deep curing, maintains stable performance in extreme temperatures, and is widely applicable to high-end, high-temperature industrial scenarios.

6. Cost-Effective: High mold cycle life (100~120 times), reducing replacement costs; stable batch quality ensures consistent production, reducing defect rates.
How to Use (Step-by-Step for High-Temperature Application)
1. Mix Part A and Part B of the platinum cure high temperature resistant LSR in a 1:1 weight ratio, stirring thoroughly for 2~3 minutes in an irregular direction until uniform and bubble-free, ensuring full integration to maintain high-temperature performance.
2. Perform vacuum degassing for 2~5 minutes to eliminate bubbles, which can affect product quality and high-temperature stability.
3. Pour the degassed silicone into molds slowly, leveraging good fluidity to fill all details and gaps, ensuring uniform thickness.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure at 150℃ for 1 hour to enhance high-temperature resistance for extreme scenarios.
5. Store unused silicone in sealed packaging, indoor storage away from sunlight and rain, use within 10 months; avoid high-temperature storage to prevent premature curing.
Application Scenarios
Our Platinum Cure High Temperature Resistant LSR is widely used in global high-end high-temperature application fields, including industrial high-temperature components (such as those for tire and cable industry accessories requiring heat resistance similar to anti-aging agents), medical accessories, precision mold making, high-temperature resin casting, metal crafts, and high-end electronic encapsulation. It is also suitable for high-temperature lubrication-related mold manufacturing and precision manufacturing scenarios, bringing tangible value: meeting strict high-temperature standards, reducing product defect rates by 40%+, extending service life, and helping B2B purchasers enhance competitiveness in high-end industrial, medical, and precision manufacturing markets.
