Rubber Material

We stock a diverse selection of rubber materials, each offering unique properties. Your part's success is reliant on choosing the right material – an aspect where our expertise ensures optimal selections.

Rubber Material Overview

Rubber Material is a material with high elasticity and plasticity, which is widely used in industrial and consumer products. According to the source, rubber can be divided into natural rubber (NR) and synthetic rubber two categories:

Natural rubber (NR): Made from latex extracted from rubber trees, it has excellent elasticity, wear resistance, and tear resistance.
Synthetic rubber: prepared by chemical synthesis methods, including many types.

At Jiangzhi, we help you select the right rubber for your project and can adjust base polymers to meet your specific performance requirements. Choosing a suitable material is crucial for your rubber molding project. Read our guide on how to select the rubber material.

Advantages of Rubber Material in Manufacturing

Rubber materials offer numerous benefits in manufacturing, making them an essential choice across many industries. These advantages include:

Exceptional Elasticity

Rubber exhibits outstanding elasticity, allowing components to stretch, compress, and rebound without permanent deformation.

Durability and Wear Resistance

Rubber is highly resistant to abrasion, fatigue, and repeated stress, ensuring long-lasting performance in demanding applications.

Versatile Applications

Rubber can be engineered for diverse uses, including seals, gaskets, vibration dampeners, hoses, and protective coatings.

Chemical and Temperature Resistance

Rubber can withstand exposure to oils, chemicals, UV, and a wide temperature range, making it suitable for harsh operating environments.

The Application of Rubber Material

FAQs About Rubber Material Parts

Don't get your answer? Let’s jiangzhi answer for you!

What are the tolerances for molded rubber parts?

Most rubber parts are made with tolerances around ±0.25–0.40 mm. For more precise applications, we can adjust the tooling and design to meet tighter requirements, so your parts fit perfectly.

Which rubber has the best compression set?

If you need seals that keep their shape under long-term pressure, FFKM performs best (5–12%), with FKM and Butyl (IIR) also doing very well. We can help you choose based on your operating conditions and budget.

Can you customize the hardness (Shore A)?

Absolutely! We can adjust rubber hardness from Shore A 20 to 90, so whether you need a soft, flexible seal or a firmer, durable gasket, we can tailor it to your exact needs.

Which rubber material is best for high-temperature applications?

For high-heat environments: FFKM works up to 300°C, FKM up to 250°C, and Silicone (MVQ) up to 230°C. We can help you pick the right one based on your temperature range, duration, and exposure conditions.

What rubber offers the best oil and fuel resistance?

For oil and fuel, FKM and FFKM are top performers. NBR is a cost-effective option for less extreme conditions.

Which rubber is most suitable for outdoor, UV, and ozone exposure?

EPDM is ideal for long-term outdoor use, UV, and ozone resistance, while Silicone also holds up very well in sunlight and harsh weather.
