Platinum Cured Liquid Foaming Silicone Rubber

Product Summary

HONG YE SILICONE liquid Foaming Silicone Rubber, also known as Silicone Foam and Foamed Silicone, is a two-component addition curing RTV2 silicone. It can expand 2–7 times in volume after chemical foaming, offering uniform pores, low shrinkage and great rebound. Working steadily from -65℃ to 200℃, this eco-friendly material works with our Mold Making Silicone, Pad Printing Silicone, Electronic Potting Compound, Human Body Silicone and robot silicone to deliver complete silicone material solutions.

Product Overview

Liquid foaming silicone rubber is a dual-component heat vulcanized addition-curing silicone material. It consists of flowable A and B liquid parts, which turn into lightweight, soft and elastic foam after controlled chemical foaming. There is no limit to the thickness of finished products. It is easy to operate and maintains stable performance over long-term use, without material migration, atrophy or permanent deformation. It is a reliable flexible raw material for mass production and custom manufacturing for global manufacturers.

Technical Specifications

This foamed silicone uses 1:1 mixing ratio for A and B components. Its foaming expansion rate ranges from 2 to 7 times. It features low linear shrinkage and excellent compression recovery. The foam keeps soft elasticity under repeated high and low temperature cycles. It is non-toxic, non-corrosive and non-radioactive, with good chemical inertness, electrical insulation and flame retardant performance.

Product Features & Competitive Advantages

Adjustable high foaming ratio brings flexible density selection. The foam has evenly distributed cells and stable structure, ensuring consistent quality batch by batch. The finished foam is lightweight with comfortable touch and excellent elasticity. It adopts platinum curing formula, safe and environmentally friendly. It can withstand extreme cold and heat, with insulation and flame retardant properties, helping manufacturers reduce defective products and control production costs.

Step-by-Step Usage Guide

1. Stir component A and B separately before use to homogenize settled fillers.
2. Mix A and B at 1:1 weight ratio, stir fully for 2–3 minutes to get uniform compound.
3. Vacuum the mixed silicone immediately and use quickly, to avoid premature condensation that affects production.

Application Scenarios & Buyer Benefits

It is widely used for sealing rings, gaskets, sealing strips, foam boards, silicone foam tubes and sponge rollers for copying and printing. It also makes silicone insoles, sofa cushions, mattress pads, automotive headrests, gear covers and seat cushions. It can produce chest pads, shoulder pads, fitness accessories, maternity back cushions and children pillows. It also acts as filling material for humanoid robot silicone products. Simple processing improves production efficiency and reduces raw material waste.

Certifications and Compliance

The material meets international environmental and safety standards. Non-toxic and inert, it can be shipped safely worldwide, supporting hassle-free customs clearance for overseas buyers.

Customization Options

We can customize foaming ratio, foam density and softness according to your production requirements to match different application scenarios.

Packaging & Storage Instructions

A component: 250KG, 25KG, 200KG per drum; B component:20KG,25KG,200KG per drum. Transported as non-dangerous goods. Keep sealed and store in cool dry place. Avoid direct sunlight and high-temperature baking. Prevent contact with sulfur, nitrogen, phosphorus, heavy metals and water to avoid curing failure.

FAQ

Q1: What should I avoid during operation?

A1: Do not expose to sunlight or high heat. Keep away from sulfur, tin, lead, mercury and moisture, which will stop the silicone from curing normally.

Q2: Can I adjust foam softness?

A2: Yes, we adjust the foaming multiple to get different density and softness for your finished goods.
