Product Abstract
HongYe silicone rubber.Low Shrinkage Foamed Silicone Rubber is a two-part addition curing liquid silicone foam designed for high-precision sealing parts. This RTV Silicone Foam features ultra-low linear shrinkage, uniform cell structure and stable rebound performance. Free from thickness limitation, this liquid foamed silicone is eco-friendly, high temperature resistant and deformation-proof. It is widely used for manufacturing industrial gaskets, sealing strips and foam boards, helping factories reduce defective rates and improve sealing stability for long-term equipment operation.
Product Overview
This industrial-grade Foaming Silicone Rubber belongs to Platinum cured mold silicone and Addition Curing Silicone series. It is composed of flowable A and B liquid components, forming uniform Foam Silicone after heating vulcanization and chemical foaming. Different from ordinary Silicone Sponge, this silicone foaming material features extremely low shrinkage and no migration atrophy after molding. It supports customized thickness molding and is a core Rapid prototyping silicone material for precision industrial sealing accessories, delivering consistent dimensional stability in mass production.
Core Product Features & Advantages
1. Ultra-low shrinkage rate: Ensures precise dimension of finished foam parts, no warping or deformation after long-term compression.
2. Highly uniform foaming: Stable foaming ratio from 2x to 7x volume, even internal structure without hollow or hard spots.
3. Extreme weather resistance: Works steadily at -65℃ to 200℃, retaining soft elasticity for outdoor and high-heat equipment.
4. Excellent insulation and flame retardancy: Possesses superior electrical insulation and flame retardant properties for electronic and electrical sealing.
5. Environmentally safe formula: Non-toxic, non-corrosive and chemically inert, compliant with international industrial safety standards.
Step-by-Step Usage Instructions
1. Pre-stirring: Fully stir A component and B component separately to eliminate storage precipitation and layering.
2. Accurate mixing: Mix two parts at standard 1:1 ratio and stir thoroughly for 2 to 3 minutes for homogeneous blending.
3. Vacuum defoaming: Remove air bubbles via vacuum processing and use the mixed liquid quickly to avoid premature condensation.
Application Scenarios
This low-shrinkage Silicone Foam is ideal for precision industrial sealing. It is widely manufactured into silicone gaskets, foam sealing pads, equipment sealing strips, silicone foam plates and printer roller sponge tubes. It provides effective dustproof, waterproof, shockproof and insulating protection for mechanical equipment, electrical appliances and precision instruments, greatly improving equipment operation stability.
Precautions
Avoid direct sunlight and high-temperature baking. Keep away from sulfur, phosphorus, nitrogen, tin, heavy metals and water to prevent curing failure.
