Product Description

Rubber Strip (Sealing Strip)

A rubber strip (also called a sealing strip or gasket profile) is a long, extruded rubber product widely used in equipment, vehicles, and construction. Its primary function is to fill gaps between mating surfaces using its elasticity, providing sealing, waterproofing, dustproofing, sound insulation, vibration damping, and fixing capabilities.

Typical Application Areas

Rubber strips are used in virtually all industrial sectors.

Building & construction – Sealing doors, windows, and curtain walls for waterproofing, windproofing, sound insulation, and energy saving.
Automotive manufacturing – Sealing car doors, windows, engine compartments, and trunk lids for waterproofing, dustproofing, sound insulation, and vibration damping.
Machinery & equipment – Sealing cabinets, enclosures, and pipework to prevent ingress of dust, moisture, and fluids.
Home appliances & electronics – Door seals for refrigerators, washing machines, ovens, and electronic device housings for sealing, insulation, and vibration damping.
Rail transportation – Sealing train doors, windows, and inter-car connections to ensure air tightness and sound insulation.

Common Cross-Sectional Shapes

Rubber strips can be manufactured in various cross-sectional shapes to suit different installation and sealing needs.

Round (O-ring profile) – The most common type, used as a sealing ring or simple linear seal.
Square / Rectangular – Provides a wider sealing surface, often used for flat-surface sealing.
Custom profiles – Tailored to specific applications (e.g., U-shaped, P-shaped, D-shaped) for complex mounting structures.
Hollow / Foam – Lightweight, soft, with excellent thermal insulation, sound absorption, and vibration damping.

Common Types and Materials

The performance of a rubber strip is mainly determined by its material. Selection depends on the specific working environment (temperature, media contact, etc.).

Material Type	Key Characteristics	Typical Temperature Range	Common Applications
EPDM (Ethylene Propylene Diene Monomer)	Excellent overall performance; outstandingresistance to ozone and weathering.	-60°C~+150°C	Building windows and doors, automotivebody seals; one of the most widely usedmaterials.
Silicone (VMQ)	Superior high and low temperatureresistance; non-toxic, odourless, goodelectrical insulation.	-55°C ~ +250°C	Food and medical equipment,high-temperature ovens, electronics, andapplications with hygiene or extremetemperature requirements.
Nitrile (NBR)	Excellent oil resistance and good abrasionresistance; cost-effective common material.	-40°C ~ +120°C	Fuel lines, hydraulic systems, machinery,and other oil-contact applications.
Chloroprene (CR)	Balanced performance; good resistance toweathering, ozone, oil, and flame.	-30°C~+120°C	Outdoor exposed environments andapplications requiring oil/fire resistance.
Fluoroelastomer (FKM / Viton@)	Outstanding resistance to high temperatures, aggressive chemicals, and oils.	Up to over 200°C	Extreme environments such as aerospaceand petrochemical industries.

Dimensional Specifications and Standards

The dimensions and performance of rubber strips are governed by national standards.
Dimensional notation – For round rubber strips (O-ring profile), the specification is usually given by cross-sectional diameter (C/S). Common sizes include φ1.78 mm, φ2.62 mm, φ3.5 mm, φ5.7 mm, etc. Square strips are available in sizes such as 6×6 mm, 10×10 mm, etc.
Relevant standards:
GB/T 3672.1 – Specifies dimensional tolerances for rubber products.
GB/T 5574-2008 – Basic national standard for rubber sealing strips.
GB/T 30649-2014 – Rubber components for sound barriers (used in railways, highways, etc.).
