Foamed Silicone with Tunable Foaming Multiples

Product Description
Hong Ye Silicone HY-F Series Liquid Silicone Foam is a customizable two-component platinum-cured RTV2 liquid foamed silicone, developed for diversified industrial sealing, shock absorption, thermal insulation and gap filling projects. Covering foaming multiples from 2.4 up to 6.8 times, this series features adjustable hardness and density, with fine and uniform cell structure, stable compression performance and low shrinkage, satisfying varied manufacturing requirements for electronics, automotive, household goods and soft craft industries.

Product Overview
Also known as foamed silicone and silicone sponge, HY-F series liquid silicone foam is an eco-friendly platinum-cured dual-component silicone material. After mixing A&B components, it undergoes chemical foaming and heating vulcanization to form lightweight soft foam. There is no restriction on the thickness of finished products. Simple mixing operation brings stable batch performance, which reduces production difficulty and raw material waste, perfectly suited for mass production of flexible foam parts. As a full-line silicone manufacturer, we supply one-stop industrial silicone material solutions for global B2B purchasers.

Technical Specifications
This HY-F series silicone foam uses 1:1 mixing ratio for A and B components. The foaming expansion ratio can be adjusted from 2.4 to 6.8 times, with controllable density ranging from 0.160 ~ 0.513 g/cm³. The cured foam maintains stable elasticity within -65℃ to 200℃ temperature range. Non-toxic, odorless and chemically inert, it has outstanding electrical insulation performance and excellent weather resistance, complying with mainstream international industrial safety standards.

Product Features & Competitive Advantages
Compared with conventional foam materials, our HY-F series liquid silicone foam can realize adjustable foaming ratio and hardness. The cured foam has fine uniform pores, no migration and no atrophy under long-time compression. It owns good cold and heat resistance, shock absorption and thermal insulation capacity to cope with complicated working environments. Adopting environment-friendly formulation, it supports safe contact application. Strict batch testing ensures stable and consistent quality, just like our mold making silicone and pad printing silicone, helping customers reduce reject rate and long-run manufacturing cost.

Application
Scenarios & Buyer Value This material is widely used to produce industrial sealing gaskets, sealing strips, foam sheets and sponge rollers. It is also applied to fabricate automotive interior buffer parts, soft cushions, silicone insoles, children’s soft pillows and fitness accessory components. Besides, it can act as high-performance filling material for robot skin and craft artwork. The easy processing workflow helps global manufacturers raise production efficiency and cut raw material consumption.

Step-by-Step Operation Guide

1. Fully stir component A and B separately to eliminate material stratification caused by long-term storage.
2. Mix the two components at 1:1 ratio and stir evenly for 2–3 minutes to ensure full blending.
3. Conduct vacuum defoaming and use the mixed glue immediately to avoid premature curing.

Certifications & Compliance
The product complies with ISO9001, CE and RoHS international quality and environmental standards. Every batch will go through strict lab tests before production and pre-shipment inspection to guarantee stable performance for worldwide industrial use.

Customization Options
Customizable foaming ratio, hardness, viscosity and formula parameters are available to meet personalized production requirements for different working scenarios.

Packaging & Storage
Instructions Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Transported as non-dangerous goods. Store in sealed, cool and dry environments. Avoid sunlight exposure, high-temperature baking and contact with water, sulfur, phosphorus and heavy metal impurities.

FAQ
Q1: What causes curing failure of addition curing liquid silicone foam?
A1: This platinum-cured silicone foam is sensitive to specific impurities. Contact with water, sulfur, tin and heavy metal substances will inhibit curing. Long-term sun exposure and high-temperature baking will also damage structural stability.

Q2: What is the difference between different models in HY-F series?
A2: We provide multiple grades from F662 to F667. The foaming ratio gradually rises while density and hardness decrease. Customers can select proper grades according to target softness, density and compression deformation requirements.

Q3: Why choose our HY-F series foamed silicone over competitors?
A3: Our HY-F series offers a complete product portfolio covering 2.4~6.8 times foaming multiples, uniform pore structure and controllable compression performance, with full international certifications and consistent batch quality.
