Determinations to Be Made at the Product Development Stage
Since we have started our research, development and manufacturing of industrial rubber products 80 years ago, there have been numerous breakthroughs. All of our accumulated experiences from formulation to production enable us to manufacture the high quality product to customer’s satisfaction.
Our company is ready to develop the industrial rubber product in compliance with the customer’s requirements throughout our entire stage starting from the rubber compound formation design that is unique to our company, verifying the required product specifications up to design verification.

01 Product
Preparation of Formulation and Raw Materials
Optimal materials are prepared not only for the general industrial rubber but also for the special purpose rubber while taking our unique compounding technology into consideration.
e.g.
- Glazing
- Zipper gasket
- Window barrier
- AT material
- Gasket for PC

02 Rubber Characteristics
Preparation of Formulation and Raw Materials
Wide range of raw rubber are prepared from EPDM having high weathering resistance, the nitrile rubber (NR) having high oil resistance up to the special fluoro-rubber to suit client demand.
e.g.
- NR: Natural rubber
- CR: Chloroprene rubber
- EPDM: Ethylene propylene diene monomer rubber
- Q: Silicone rubber
- BR: Butadiene rubber
- SBR: Styrene-butadiene rubber
- NBR: Nitrile rubber
- FKM: Fluoro-rubber
- IIR: Butyl rubber
- U: Urethane rubber
- ACM: Acrylic rubber

03 Mechanical Properties
Investigation on the Demand Performance
New material can be development to supply the rubber that can withstand the severe environment from -40°C to +140°C or even more severe condition.
e.g.
- Hardness
- Tensile strength
- Elongation
- Impact elasticity
- Compression set
- Tear strength
- Abrasion resistance
- Flex-crack resistance

04 Physical Properties
Physical Performance : Investigation on the Demand Performance
Sponge with low compression-reaction (low load value), Low elongation (difficult to stretch) rubber / Low impact elasticity rubber, Low compression set rubber. We will develop the formulation and compounding ingredients that meet the client demand and requested performance.
e.g.
- Heat-resisting property
- Low-temperature resisting property
- Anti-aging property
- Weathering resistance property
- Ozone resistance property
- Flame-resistance property
- Electrical insulation property
- Gas anti-permeation property
- Radiation resistance property
-
05 Compounding ingredients
Compound formation design in compliance with customer’s need and required performance
The compound formation is designed in compliance with customer’s need and required performance.
e.g.
- Vulcanizing agent (cross-linking agent)
- Vulcanizing accelerator
- Antidegradant
- Rubber stiffener
- Rubber softener
- Plasticizer
- Forming agent
- Rubber flame retardant
- Filler

06 Production Line
Our production line is based on the "Kanban System" centered on the Toyota Production System to manufacture products according to customers’ demands by eliminating waste.
e.g. Compounding -> Kneading -> Extrusion -> Molding -> Inspection -> Shipment
