Rubber components fail quietly — a seal that hardens, a gasket that cracks, a tyre compound that wears too fast. By the time the symptom shows up in the field, the cost is already high. That is why manufacturers across Chennai turn to Kiyo R&D Lab to verify the physical and ageing properties of their rubber and elastomer products before they ship.
From hardness and tensile strength to compression set, abrasion, and accelerated ageing, we run the full range of rubber tests on calibrated equipment to recognised ASTM, ISO, and IS methods. The result is clear, defensible data that your quality, design, and compliance teams can act on with confidence.
Rubber and elastomers behave very differently from metals and plastics. They flex, recover, harden with age, swell in oils, and degrade under heat, ozone, and sunlight. A compound that performs perfectly on day one can lose its sealing force or split within months if its properties are not verified. Testing catches these weaknesses before they reach the customer.
For manufacturers of seals, gaskets, hoses, tyres, footwear, and automotive parts, rubber testing is the proof that a product will hold up in real service conditions. It also satisfies customer specifications, supports certification, and gives R&D teams the data to validate new compounds or supplier changes with confidence.
Kiyo R&D Lab tests natural rubber, synthetic elastomers, and finished rubber products across a wide range of properties, with documented procedures at every step. Below are the categories we test most often.
Shore A and Shore D durometer measurement to verify the firmness of rubber compounds.
Tensile strength, modulus, and elongation at break for vulcanised and thermoplastic rubber.
How well a seal or gasket recovers its shape after prolonged compression and heat.
Heat ageing in air ovens to predict how properties change over the product’s life.
Wear and material loss testing for soles, tyres, rollers, and high-friction parts.
Specific gravity and fluid/oil resistance to confirm compound behaviour in service.
Trustworthy results depend on traceable methods. We test to internationally recognised rubber standards so your reports are accepted by customers, auditors, and certification bodies alike.
ASTM ISO IS (BIS)
