1:1 Mix Ratio Food Grade Platinum Cure Silicone Rubber

HY-PT1-1-30 is a premium food grade platinum cure (addition cure) silicone rubber featuring the industry's simplest 1:1 equal-part mixing ratio. No complicated measuring, no catalyst percentage calculations — just mix equal parts of A and B and pour. This user-friendly formulation eliminates mixing errors and delivers consistent, bubble-free molds every time.

Why 1:1 Mixing Ratio Matters

• Eliminates Mixing Errors: Equal-part mixing removes the guesswork from traditional 100:2 or 100:5 ratio systems. Perfect for operators of all skill levels.
• Faster Production Setup: Simply weigh equal amounts of Part A and Part B — no catalyst calculations needed. Saves 30-50% setup time per pour.
• Consistent Results: 1:1 ratio ensures uniform curing across all batch sizes, from small 100g pours to large 20kg production runs.
• Reduced Waste: Operator errors from incorrect catalyst ratios are eliminated, reducing material waste and rework costs.

Key Features

• Food Grade Certified: Complies with FDA 21 CFR 177.2600 and LFGB standards for food contact applications. Safe for chocolate, candy, ice, soap, and baking molds.
• Crystal Clear Transparency: Ultra-transparent formulation lets you see your casting inside the mold, making it easier to position inserts and detect bubbles.
• Platinum Cure — No Byproducts: Addition cure chemistry produces no harmful byproducts during curing. Odorless, non-toxic, and safe for enclosed workspaces.
• Adjustable Hardness (10-30 Shore A): Available in multiple grades from ultra-soft 10A for intricate chocolate molds to 30A for sturdy soap and candle molds.
• Low VOC (<0.5%): Ultra-low volatile organic compound content meets the strictest environmental standards.
• High Tear Strength (≥22 kN/m): Industrial-grade durability for hundreds of demolding cycles without degradation.

Typical Applications

Technical Advantages

• Temperature Range: Performs reliably from -40°C to +200°C, suitable for freezing and baking applications.
• High Elongation (≥500%): Makes demolding intricate shapes effortless — mold stretches and returns to shape without tearing.
• Fast Demolding: Cures in 2-4 hours at room temperature; can be accelerated to 30 minutes with mild heat (60-80°C).
• Non-Stick Surface: Platinum silicone inherently releases most casting materials without mold release agents.
• Bubble-Free Pouring: Low viscosity (5000-15000 mPa·s) combined with excellent air release for vacuum-free operation in many applications.
