This constitutes the core stage for achieving material uniformity and purity.
Compounding Uniformity: It is imperative that all components (raw rubber, silica, colour masterbatch, additives) are thoroughly and uniformly blended within the internal mixer or open mill. Any inconsistency will result in silicone sheets exhibiting uneven hardness, colour variation, surface particles or pitting, and potentially internal weak points.
Filtration (Critical): For silicone sheets requiring high purity (e.g., medical, food-grade, optical-grade applications), the compounded material must undergo filtration through mesh screens. This step removes potential impurities, dust, or undispersed rubber lumps, significantly enhancing product cleanliness and surface quality. Mesh mesh count is selected according to specific requirements.
