Indian rubber becomes really brittle with age and it cracks and it falls off, exposing live electrical cables, which is a real fire risk.
Material for hot vulcanised
rubber mats with textile insertion for general use;
The tyre, which is made from APILON 52 polyurethane resin from API, is said to offer technical and functional advantages, such as superior wear and tear resistance and improved elasticity for agricultural use, where prolonged abrasion caused by the ground causes tyres that are normally made in vulcanised rubber to wear down quickly.
The APILON 52 tyre weighs between 20 and 50 percent less than conventional vulcanised rubber tires, resulting in lower fuel consumption.
E2 features vulcanised rubber wheels mounted on a polypropylene technopolymer centre with a precision tube axle set and zinc plated bracket assembly including a dual ball race configuration.
For more specialist applications the RE-C7 is a high quality item, with its grey anti-marking vulcanised rubber tyres, thread guard, dual race ball bearing bracket and total lock option which is likely to meet requirements for use in general public utilities, e.
Although TPEs have been synthesised to mimic the properties (mechanical and chemical) of traditional vulcanised
elastomers they perform less well at elevated temperatures, as one might expect.
