Platinum Catalyst TPL/PTR Series

Product Summary

Our Platinum Catalyst (TPL & PTR series) is a transparent liquid catalyst designed for hydrosilylation reactions in addition-cure liquid silicone systems. With platinum content ranging from 1000 to 5000 ppm, viscosity of 320–1000 mPa·s, and low volatile content (3%–10%), it enables efficient curing at room or elevated temperatures. Suitable for electronic encapsulants, photovoltaic modules, automotive seals, and adult/food-grade silicone products. Backed by ISO9001 certification and a utility model patent (ZL202323622488.5), our catalyst ensures consistent batch quality and reliable performance.

Key Selling Points

• High Catalytic Activity – Platinum content from 1000 to 5000 ppm allows low addition rates, reducing formulation costs while achieving rapid curing.
• Excellent Batch Consistency – Uniform platinum distribution minimizes activity fluctuation, ensuring stable feel, hardness, and curing speed across batches.
• Versatile Formulation Adaptability – Compatible with low-odor, medical-grade, and food-grade silicone systems; leaves no residual odor and does not affect biocompatibility.
• Proven Efficiency Gains – Client case studies show a 30% increase in curing efficiency, 25% higher batch capacity, and defect rate reduction from 2.5% to 0.6%.
• Comprehensive Technical Support – Formulation optimization and process debugging assistance to resolve uneven or delayed curing issues.

Materials and Structure

Composed of platinum (Pt) dispersed in a siloxane or alcohol solvent. The catalyst is homogeneous and fully miscible with addition-cure silicone systems, ensuring uniform distribution.

Applications

• Electronic & electrical appliance industry (keypads, seals, potting compounds)
• Photovoltaic technology (encapsulants, junction box potting)
• Automotive industry (gaskets, sensors, high-temperature seals)
• Adult and food-grade silicone products (realistic dolls, kitchenware)
• Medical-grade silicone (non-leaching, biocompatible formulations)

Customization

We offer tailored platinum content, viscosity, and packaging to meet specific process requirements. Contact our technical team for custom formulations.

Case Study

Client A: A large liquid silicone manufacturer in the Pearl River Delta used our catalyst for adult realistic silicone. After switching, their curing efficiency increased by 30%, production batch capacity rose by 25%, and defect rate dropped from 2.5% to 0.6%. Annual purchase volume: 80 kg.

Client B: A top organosilicon group sourced 500 kg annually for food-grade and electronic silicone products. Stable supply over 3 years, with no yellowing or leaching issues.
