HONGYE SILICONE’s liquid silicone Seals And Gaskets are premium dual-component Addition Curing Silicone products, tailored for global B2B purchasers in automotive, electronic, industrial equipment, and food & medical industries. As a national high-tech enterprise with standardized production and one-stop solutions, our seals and gaskets feature excellent sealing performance, wide temperature resistance, high durability, and FDA/RoHS compliance. They support room/heat curing, flexible customization, and tight sealing for diverse scenarios, helping purchasers prevent leakage, extend equipment service life, and meet strict industrial sealing requirements.
Product Overview
Our Liquid Silicone Seals And Gaskets are high-performance sealing solutions, crafted from high-purity flowable Part A (base rubber) and Part B (curing agent) via advanced addition curing technology. They solve the pain point of ordinary seals/gaskets (such as rubber or low-grade liquid silicone) with poor sealing, easy aging, and limited temperature adaptability. Unlike standard Mold Making Silicone, our products are specially formulated for sealing scenarios—curing into elastic, tight-fitting seals that resist compression, tearing, and extreme temperatures, making them ideal for automotive parts, electronic enclosures, industrial equipment, and food/medical device sealing.

Product Features & Advantages
1. Superior Sealing Performance: Low compression set (≤15%) and high sealing pressure (≥1.5MPa), forming a tight, leak-proof seal, effectively preventing gas, liquid, and dust leakage.
2. Wide Temperature Adaptability: Withstands -60℃~250℃, maintaining sealing performance in extreme cold/heat, no deformation or aging, suitable for harsh industrial environments.
3. High Durability: High tensile/tear strength, wear-resistant, anti-aging, service life ≥5 years, reducing replacement frequency and costs.
4. Safe & Compliant: Advanced addition curing, non-toxic odorless, FDA/RoHS compliant, safe for food/medical and electronic scenarios.
5. Easy Operation & Customization: 1:1 mix ratio, simple stirring for 2~3 minutes; customizable shape, size, hardness, and color to match diverse sealing needs.
6. Strong Adaptability: Compatible with metal, plastic, and glass surfaces, tight fitting without damage to equipment.
How to Use (Step-by-Step Guide)
1. Mix Part A and Part B of the liquid silicone for seals and gaskets in a 1:1 weight ratio, stirring thoroughly in an irregular direction for 2~3 minutes until uniform and bubble-free (ensuring sealing effect). 2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity) to eliminate bubbles, avoiding sealing defects. 3. Pour the degassed silicone slowly into seal/gasket molds, leveraging good fluidity to fill all details. 4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure enhances sealing performance and durability. 5. Store unused silicone in sealed packaging, separate Part A and Part B, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
Application Scenarios
Our Liquid Silicone Seals And Gaskets are widely used in global industrial fields, including automotive parts sealing, electronic enclosure sealing, industrial equipment sealing, Liquid Tank Sealant, food/medical device sealing, and precision instrument sealing. They also apply to High transparency mold silicone for visible seals, bringing tangible value: reducing leakage defect rates by 55%+, extending equipment service life by 40%+, and helping B2B purchasers reduce maintenance costs and improve product reliability.
