Product Description

HONGYE SILICONE heat resistant silicone is Platinum cured mold silicone tailored for high temperature casting. This heat-stable addition curing RTV 2 Silicone Rubber uses premium Silicone raw materials to resist continuous high-temperature deformation. Unlike ordinary Condensation Curing Silicone Mold Rubber, this durable Mold Making Silicone and Rapid prototyping silicone maintains stable elasticity under repeated thermal cycles for metal casting and high-heat industrial mold projects.

Product Overview

This heat resistant Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 A/B weight ratio. Developed for high-temperature casting workpieces, it delivers stable elasticity within -60℃ to 250℃, supporting room-temperature and heating dual curing. Widely used for metal craft molds, automotive Prototype silicone , alloy casting molds, Toy mold silicone and high-temperature rapid prototyping, all formulas support personalized adjustment.

Product Features & Advantages

Premium heat-resistant formula resists thermal aging, cracking and deformation under long high-temperature casting;

Full deep curing without thickness limit, stable performance for thick large high-temperature molds;

FDA certified Food grade mold silicone, non-toxic and odorless for multi-industry casting;

High fluidity liquid silicone easily fills complex casting mold structures without dead angles;

High tensile & anti-tear strength, multiple demolding cycles to extend mold service life;

Superior thermal stability compared with common industrial Mold Silicone rubber;

Customizable color, working time and hardness for special high-temperature casting projects.

Step-by-Step Operation Guide

Mix heat resistant silicone A and B evenly at 1:1 weight ratio for 2-3 minutes;

Vacuum defoam mixed silicone for 2-5 minutes to eliminate hidden bubbles;

Slowly pour liquid RTV mold silicone into high-temperature casting molds;

Choose room temperature or heating curing based on production process;

Gently demold after full curing to complete high-temperature casting production;

Seal unused silicone and store indoors away from sunlight and rain.

Application Scenarios & Buyer Value

Ideal for high temp casting, metal craft molding, rapid prototyping silicone, alloy component and industrial toy mold silicone production. This heat resistant silicone avoids mold failure caused by continuous high temperature, cuts frequent mold replacement costs, reduces production downtime and stabilizes batch casting quality for mass manufacturers.

Certifications and Compliance

This high-temperature silicone passes FDA food grade and ISO quality certifications, meets international RTV 2 silicone rubber industrial standards, satisfies cross-border high-temperature casting material safety requirements.

Customization Options

We customize heat resistance grade, hardness, viscosity and curing cycle, offering exclusive high-temperature formulas for High transparency mold silicone and harsh thermal casting scenarios.

Production Process

High-purity silicone raw material screening → heat-resistant formula blending → constant temperature synthesis → high-temperature durability testing → strict quality inspection → vacuum sealed packaging, guaranteeing stable performance under long-term high-temperature casting.
