Product Features & Advantages

1. Ultra-low shrinkage rate, no size deviation after curing, restoring original prototype dimension;

2. Complete deep curing without thickness limit, no internal shrinkage for thick large-scale prototypes;

3. FDA certified Food grade mold silicone, non-toxic and odorless for multi-scene precision casting;

4. Excellent fluid liquid silicone, infiltrating tiny gaps to replicate micro prototype textures;

5. Reinforced tensile and anti-tear strength, long service life for repeated prototype iteration;

6. Far better dimensional stability than ordinary industrial Mold Silicone rubber;

7. Customizable curing time, color and viscosity for exclusive precise prototype projects.

Step-by-Step Operation Guide

1. Mix low shrink silicone A and B components evenly at 1:1 weight ratio for 2 to 3 minutes;

2. Conduct vacuum defoaming for 2-5 minutes to avoid bubble-induced partial shrinkage;

3. Pour liquid RTV mold silicone into precise prototype molds slowly;

4. Select room temperature or heating curing according to precision production demands;

5. Demold steadily after full curing to prevent artificial dimensional deformation;

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

Application Scenarios & Buyer Value

Suitable for precise prototype molds, industrial rapid prototyping silicone, miniature craft molds, automotive accessory and precision toy mold silicone production. This low shrink silicone reduces dimensional error and prototype rework rate, cuts material waste, improves finished product qualification rate, and helps manufacturers obtain high-precision industrial orders.

Certifications and Compliance

This high-stability silicone passes FDA safety certification and ISO industrial quality certification, complies with international RTV 2 silicone rubber manufacturing standards, meeting cross-border precision prototype material tolerance requirements.

Customization Options

We support customized shrinkage rate, hardness, transparency and curing cycle, supplying high-precision formulas for High transparency mold silicone and dimensional-sensitive prototype projects.

Production Process

Low-shrinkage silicone raw material screening → stability formula compounding → constant temperature synthesis → dimensional tolerance testing → finished product calibration → vacuum sealed packaging, eliminating curing shrinkage for precise mold making.

FAQ

Q1: What is the actual shrinkage rate of this silicone?

A1: Ultra-low shrinkage below industry average, negligible dimensional deviation.

Q2: Will thick prototype shrink unevenly?

A2: Uniform deep curing avoids local deformation and shrinkage.

Q3: Can it replicate micron-level prototype details?

A3: Low-shrinkage + high fluidity ensures full texture restoration.

Q4: Can adjust shrinkage for ultra-precision molds?

A4: Professional low-shrinkage customization is available.

Q5: Does storage affect dimensional stability?

A5: Sealed dry storage keeps stable performance for 10 months.
