MetadataShow full item record
Dispersed calcium carbonate filler on mechanical properties of natural rubber latex films were investigated. Natural Rubber latex film Preparation of natural rubber (NR) latex films by dipping cleaned formers into latex compound containing curatives and filler. Latex formulation as Sulfur, ZDEC, ZnO and calcium carbonate filler was add to pre-vulcanized latex compound. The resulting films were dried at 100 ºC and drying time 10 minutes. The effect of filler content on modulus, tensile strength and elongation at break was investigated.
