A high mu rubber (fomerly termed high hysteresis, high energy-loss or ‘cling’ rubber) is one specially developed for the wearing surface of pneumatic tyre treads to improve road holding. Mullins Effect Work done by L. Mullins on the prestressing of filler-loaded vulcanisates showed that such prestressing gives a stress-strain curve. Rubber Compounding Chemistry and Applications edited by Brendan Rodgers The Goodyear Tire & Rubber Company Akron, Ohio Oil-extended natural rubber. Oil-extended natural rubber (OENR) treads are very eﬀective in improving ice grip and snow traction of tires and have been reported to be used for service in northern Europe. OENR is produced Author: Quang Hoang.
The dependence of fatigue life on the depth c of an initial defect or flaw is also large, and different for different materials. For natural rubber compounds the fatigue life is seen to be approximately proportional to 1/c, and thus is decreased by a factor of 2 if the depth of an accidental flaw is increased by a .

There is a relationship between the static deflection imposed on the rubber mount springing by the suspended mass and the rubber's natural frequency of vibration, which may be given by Engine and transmission vibrations 30 n0 p x Natural frequency of vibration (Fig.

Rubber stress-strain curves under static conditions are concave toward the load axis, i.e., strain hardening, except for a short portion near the origin. The concavity is accentuated by the occurrence of stressinduced crystallization in natural rubber at higher elongations [32, 33]. There is no yield point before failure, as is usual with metals.5/5(1).
Natural rubber was also used extensively in its oil-extended form in winter tires in the s (57). Use of oil-extended natural rubber treads, found to have excellent traction on ice and snow, superseded studded synthetic rubber treads when studs were banned in certain countries and states owing to the damage they cause to partially cleared roads.LANXESS India Private Limited Business unit - Rubber Chemicals Rubber Technical Center 1 s t Floor,Plot No.A/,16 t h Road V, MIDC, Wagle Industrial Estate, Thane(W),Maharashtra, India Tel: +91 22 Tel: +91 22 / 2 Fax: +91 22 E-Mail: @ Mobile:+91 /5(1).evaluation of natural rubber: presented at the fifty-fifth annual meeting [fiftieth.
