Product Description

HONGYE SILICONE high stretch silicone is premium Platinum cured mold silicone customized for soft flexible products. This elastic addition curing RTV 2 Silicone Rubber adopts high-elasticity Silicone raw materials, featuring ultra stretching performance and resilient recovery. Compared with rigid Condensation Curing Silicone Mold Rubber, this functional Mold Making Silicone and Rapid prototyping silicone fits elastic craft, wearable and bendable product mass manufacturing perfectly.

Product Overview

This high stretch Liquid Mold Silicone is two-component Industrial mold silicone rubber with 1:1 weight mixing ratio. Optimized for soft flexible finished goods, it balances superb ductility and structural stability, supporting room-temperature and heating dual curing modes. It is widely applied to Shoe mold silicone , elastic Toy mold silicone , Human Body Silicone , flexible Prototype silicone and bendable crafts molding, with customizable formula.

Product Images and Videos

1. Excellent high-stretch performance with strong rebound ability, no permanent deformation after repeated bending;

2. Full deep curing without thickness limit, keeping uniform elasticity for thick flexible molds;

3. FDA-certified Food grade mold silicone, non-toxic and odorless for wearable and skin-contact products;

4. Superior fluidity liquid silicone for smooth pouring and delicate flexible detail replication;

5. Reinforced tensile and anti-tear strength, resisting breakage during demolding and stretching;

6. Better ductility and flexibility than ordinary rigid industrial Mold Silicone rubber;

7. Adjustable elasticity, color and curing time for personalized soft flexible products.

Product Features & Advantages

Step-by-Step Operation Guide

1. Blend high stretch silicone A and B components evenly at 1:1 weight ratio for 2-3 minutes;

2. Conduct vacuum defoaming for 2-5 minutes to eliminate tiny bubbles;

3. Pour liquid RTV mold silicone into molds for soft flexible products steadily;

4. Select room temperature natural curing or high-temperature fast curing as required;

5. Demold slowly after full curing to protect elastic structure;

6. Seal leftover silicone and store indoors, avoid sunlight and rain erosion.

Application Scenarios & Buyer Value

Suitable for soft flexible products production, rapid prototyping silicone, shoe mold silicone, elastic toy accessories and skin-friendly flexible crafts. This high stretch silicone reduces product fracture and defective rate, cuts material waste, extends mold service life, and helps manufacturers produce high-quality elastic goods to expand product lines.

This elastic stretchable silicone passes FDA food grade certification and ISO industrial quality certification, complies with international RTV 2 silicone rubber safety standards, meeting cross-border flexible consumer goods manufacturing requirements.

Certifications and Compliance

Customization Options

We support customization of stretch strength, softness, viscosity and color, supplying exclusive elastic formulas for High transparency mold silicone and all kinds of bendable flexible products.

Production Process

High-elastic silicone raw material screening → stretch reinforcement formula blending → constant temperature synthesis → elasticity fatigue testing → strict quality inspection → vacuum sealed packaging, ensuring stable stretching performance for soft product molding.
