It features userfriendly operation with dual curing options, providing onestop mold manufacturing solutions. Widely applied in highgrade simulated food molds, metal crafts, alloy car accessories, epoxy/polyester resin molds, large cement components, cultural stones, concrete molds, highprecision handboard models, and rapid prototyping, it can also be tailormade according to customers’ specific technical requirements.
Technical Specifications
Material Type: Twocomponent Addition Curing Silicone rubber Mixing Ratio: Part A : Part B = 1:1 (by weight) Operating Time (25℃): 30~40 minutes (customizable) Curing Time (25℃): 4~5 hours; 80~120℃: tens of minutes (customizable) Temperature Resistance: 60℃ ~ 250℃ Certifications: FDA (food contact), ISO9001, CE Shelf Life: 10 months (sealed storage in indoor, dry environment)
Product Features & Advantages
Based on advanced additioncuring technology, this silicone rubber has obvious advantages over condensation curing alternatives, such as deeper curing depth and lower shrinkage rate.
Key features: 1. Deep curing performance, no limitation on the thickness of mold products.
2. Foodgrade standard, nontoxic and odorless, passed FDA certification for safe contact with food.
3. Excellent high and low temperature resistance, maintaining stable elasticity in extreme environments.
4. Strong fluidity for easy pouring and precise replication of fine details; dual curing methods meet different production rhythms.
5. Higher tensile strength and tear resistance than ordinary Mold Silicone, enabling more demolding times and longer service life. 6. Customizable color, operating time, and curing time to adapt to diverse production needs. Supported by over 20 years of silicone manufacturing experience, the product quality is stable and reliable.
How to Use
1. Prepare Part A and Part B in a 1:1 weight ratio, stir thoroughly for 23 minutes until the mixture is uniform.
2. Conduct vacuum defoaming treatment for 25 minutes (adjust time according to silicone viscosity, weight, and vacuum intensity).
3. Pour the uniformly mixed silicone into the mold frame slowly and evenly.
4. Cure at room temperature (25℃) for 45 hours, or heat at 80120℃ for accelerated curing.
5. After complete curing, demold gently and start formal production.
Customization Options
We provide comprehensive customization services to meet personalized needs: Formula customization: Adjust viscosity, hardness, and tear resistance according to specific application scenarios.
Color customization: Offer transparent, white, or other customized colors as required.
Process parameter customization: Tailor operating time and curing time to match customers’ production lines.
Packaging customization: Provide flexible packaging specifications based on order quantity and logistics conditions.
Production Process
The production strictly follows quality control standards: raw material inspection (highpurity Silicone raw materials, platinum catalysts) → precise proportioning and mixing → vacuum degassing → automatic filling → finished product performance testing (viscosity, curing speed, tensile strength) → sealed packaging. Equipped with 20 professional production lines and a dedicated quality inspection team, we ensure that each batch of products meets the set standards and can fulfill bulk orders with ontime delivery.
