Silicone Resin
Everything you need to know about our products and company
Silicone resin represents a critical class of synthetic polymers characterized by a backbone of alternating silicon and oxygen atoms with organic side groups. The purity standard of high-purity silicone resin is primarily determined by the industrial application requirements and regulatory compliance needs. While specific purity percentages for silicone resin aren’t standardized like metallic silicon grades (which can reach 99.999% for semiconductor applications), the quality is controlled through parameters such as ionic contamination levels, catalyst residues, and by-product elimination .
The manufacturing process for high-purity silicone resin involves sophisticated purification technologies to achieve impurity levels below critical thresholds. For electronics applications, this often means contaminant control at parts-per-billion (ppb) levels, particularly for metals like sodium, potassium, and iron that can compromise electrical properties. The R/Si ratio (organic groups to silicon atoms) typically maintained between 1.2-1.6 in practical silicone resins, significantly influences both purity and performance characteristics .
Globally, silicone resins must comply with various industry-specific standards that indirectly define purity requirements through performance specifications. Key standards include:
Biyuan’s manufacturing facilities adhere to these international standards while implementing stringent quality control measures that exceed basic requirements. Our compliance with REACH, RoHS, and FDA regulations ensures that our high-purity silicone resins meet global market demands .
The semiconductor industry consumes over 40% of global ultra-high purity materials, with silicone resins playing critical roles in encapsulation, insulation, and protection applications. Semiconductor-grade silicone resins require impurity levels below 1 ppb for metallic contaminants to prevent device failure .
