Materials for Rubber Seal Strips

Rubber seal strips come in various materials, which provide specific performance based on the application.

EPDM rubber  with excellent weather resistance, high resistance to UV, ozone, and weathering. Which can withstand temperatures from -40°C to +120°C. EPDM rubber material with good flexibility, retains flexibility in various temperature ranges. Material with excellent water and air-tight sealing properties, ideal for doors, windows, and industrial uses.

Rubber seal strip shapes: Common in D-shaped, P-shaped,L-shaped and other shapes extruded profiles.

Usage: Automotive, construction (windows, doors), outdoor seals (gardens, machinery), and roofing.

Neoprene rubber (CR) with good weather and ozone resistance, chemical resistance and flame resistance. Material can be widely used in automotive seals, refrigeration seals, industrial equipment and marine applications.

Nitrile rubber (Buna-N) with excellent oil and fuel resistance and cold resistance, which provides a good balance of flexibility and durability. NR material product can be widely used in automotive fuel seals, industrial machinery.

Silicone rubber material with wide temperature range: withstands extreme temperatures (-50°C to +250°C), UV and ozone resistant, and non-toxic. Silicone seal strip with high flexibility, can stays flexible in both hot and cold environments.

Usage: used in high-temperature environments, food and medical equipment seals, and outdoor weatherproofing.

PVC material in less flexible than materials of EPDM and silicone, but also in good chemical resistance.

How to choose available Rubber Seal Strips?

Choose correct rubber seal strips not only based on ideal design, material choose is also the most important. We already know the properties of various material, but how to choose available rubber seal strip? All of rubber seal strips must meet following properties,

1) Good elasticity and compression set, because high elasticity ensures better performance in sealing gaps and flexibility over time.

2) Durability and Weather Resistance: Rubber seal strips should resist UV, ozone, and other environmental factors. EPDM material is an ideal for weather-resistant applications.

3) Chemical and Oil Resistance: Nitrile and neoprene rubber seals are better in environments exposed to oils, fuels, and chemicals, while silicone and EPDM are less effective in these conditions.

4) Temperature Resistance: silicone material have excellent temperature resistance, ranging from very low to very high extremes, making them ideal for applications in harsh temperature environments.

5) Water and Air Tightness: Rubber seal strips should provide a tight barrier to prevent water, air, and dust from entering. This is especially crucial in automotive, construction applications.

How to Choose the Right Material for Rubber Seal Strips?

When selecting the right material for your rubber seal strip, consider the following factors:

Outdoor Use or indoor use, temperature range, exposure to chemicals or not, flexibility and durability and cost.

Potential Applications

Widely used on automotive seal doors, windows, sunroofs, and trunks to protect the vehicle's interior from dust, moisture, and noise.
