 PROTECTIVE EFFECTS

SUNOC gives better results than other ozone protective waxes. The use of high quality special waxes is urgently recommended when products are going to be exposed to ozone at fairly high temperature. It forms a sort of membrane barrier between the rubber article and the environment. This physical barrier is a film of wax which forms on the surface of the vulcanizates. SUNOC is efficient in preventing ozone cracking, particularly under static conditions, but in view of waxes acting, the most important factor is that wax film will remain intact fairly long.

SUNOC 較其它臭氧保護蠟效果更好。當產品在相當高的溫度下暴露於臭氧時,迫切需要使用高品質的特殊蠟。它在橡膠製品與環境之間形成一種薄膜屏障。這種物理屏障的蠟膜,在硫化物表面形成。SUNOC在抗臭氧龜裂方面是有效的,特別是在靜置條件下。但鑒於蠟的作用,其最重要的因素是蠟膜將可保持相當長的完好無損。
