Product Material

Material is selected for the media, temperature and mechanical demands of each part. We offer:

NBR (Nitrile Rubber): good resistance to mineral oils and greases at a competitive cost; standard range −40°C to 100°C.
HNBR (Hydrogenated Nitrile): higher heat, wear and aging resistance than NBR for heavy-duty use; standard range −40°C to 150°C.
FKM (Fluoroelastomer): excellent resistance to high temperature, fuels and aggressive fluids; standard range −25°C to 250°C.
ACM (Acrylic Rubber): good resistance to hot engine and transmission oils; widely used in Japanese vehicle designs.
EPDM: excellent resistance to water, steam, weathering, ozone and glycol-based brake fluids; not suitable for mineral oils or fuels; standard range −55°C to 125°C.
Silicone (MVQ): very wide temperature range and good flexibility, best for static or low-wear applications; standard range −60°C to 225°C.
SBR: economical general-purpose rubber for water and air; not oil-resistant.

Special compounds can be developed for your operating conditions, and our engineers will recommend the most suitable material for your application.

Our Advantages

1. Low tooling cost: molds already exist for most standard sizes, so no tooling investment is needed. For special sizes we keep mold costs low or co-develop the tooling with you.
2. Flexible MOQ and fast delivery: small orders and sample testing are supported, and stocked items ship quickly so you can plan production with more flexibility.
3. Automatic inspection: automatic inspection equipment introduced in 2020 removes the bottleneck of manual inspection and keeps quality consistent.
4. Custom development: send your drawing (CAD) or a sample and our engineers will propose the part design and material.
