Sulfur vulcanization
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and electronic properties. Many products are made with vulcanized rubber, including tires, shoe soles, hoses, and conveyor belts. The term vulcanization i

COMPARING STRENGTH PROPERTIES OF NATURAL AND SYNTHETIC
The properties of natural rubber mixtures are the followings: - high static tensile strength (15-22 MPa), - high elongation (600-900%), - excellent elasticity at low temperature (up to – 10 0C doesn’t change substantially) - poor ozone and degradation stability, - good confectionability because of excellent crude adhesion.

Effect of nature and extent of crosslinking on swelling
Abstract The influence of crosslink type and crosslink density on the swelling and mechanical behavior of styrene–butadiene rubber (SBR) membranes were studied in four aliphatic hydrocarbons. To vary the crosslink type and crosslink density, SBR was vulcanized by four different vulcanizing systems viz conventional, efficient, peroxide and a mixture of sulfur and peroxide.

Effect of temperature on sulfur prevulcanization
Sulfur prevulcanization of natural rubber latex was conducted at 60, 70, 80, and 90°C for different periods. The extent of crosslinking was assessed. Tensile properties, water absorption, leaching, and stress‐relaxation characteristics of the films were also evaluated.

Abstract: Natural rubber (NR) was foamed at different feeding ratios of carbon black and different foaming pressures. The cure characteristics were studied with respect to the carbon black content, and the effects of the foaming pressure and filler loading on the mechanical properties and morphologies of the foams were also investigated.
