Solid rectangular silicone sealing strip

Product Description

Product Overview

The solid rectangular silicone sealing strip is manufactured from high-purity silicone raw material through high-temperature extrusion and vulcanization. Featuring a solid rectangular cross-section, it is dense with no air bubbles, highly resilient, and exhibits excellent rebound. It offers multiple performance characteristics, including resistance to extreme temperatures, water and dust tightness, sealing and cushioning, as well as electrical insulation and soundproofing. It is ideally suited for sealing and impact‑absorbing applications in doors and windows, cabinets, mechanical equipment, electrical enclosures, automobiles, and more.

Product Features

Excellent high- and low-temperature resistance
Suitable for temperatures ranging from **–40°C to 250°C**: it remains flexible and does not crack at low temperatures, nor deforms or ages at high temperatures, ensuring stable performance throughout all seasons.
Solid, highly elastic, and tightly sealed.
Solid rectangular structure with rapid compression recovery, ensuring tight sealing and effective protection against water, dust, wind, noise, and impact.
Age-resistant and weatherproof, with a long service life.
UV‑resistant, ozone‑resistant, and weather‑ and sun‑proof; suitable for long‑term outdoor use without chalking, cracking, or discoloration.
Eco-friendly and safe, non-toxic and odorless.
Food-grade or industrial-grade options available; odorless and non‑polluting, compliant with RoHS environmental standards; suitable for use around household appliances, electrical devices, and food‑processing equipment.
Insulation and flame-retardant properties are stable.
Excellent insulation performance, moisture-resistant and leak-proof, ideal for insulating and sealing electrical cabinets and equipment.
Wear-resistant and tear-resistant
The material is dense and durable, resistant to abrasion and tensile stress, and maintains its shape; it remains resilient even under prolonged compression.

Scope of Application

Door and window seals, aluminum alloy profiles, and wooden door and cabinet door sealing for impact protection.
Waterproof and dustproof sealing for distribution cabinets, enclosures, and cabinet-mounted equipment.
High-temperature-resistant sealing for ovens, sterilization cabinets, and household appliances
Automotive, construction machinery, and locomotive door frame buffer sealing strips
Chemical equipment, insulated enclosures, and shock-absorbing seals for cold storage doors

Product Advantages

Solid construction ensures no deformation, with superior resistance to high temperatures and weathering; it integrates sealing, sound insulation, and impact protection. Customizable specifications, easy installation, and excellent cost-effectiveness make it suitable for industrial, residential, and appliance applications—durable and versatile.
