Two decades of dedication to organosilicon and polymer materials — building industrial partnerships through precision chemistry
Cornerstone New Materials Co., Ltd. is a high-tech enterprise specializing in R&D, production, and sales of silicone materials and specialty chemicals. Our core technical team brings over two decades of hands-on experience across specialty silicone synthesis, polymer additive formulation, and thermoplastic elastomer processing.
From day one, we have been guided by a single mission: to empower downstream customers with professional, consistent, and trustworthy material solutions that elevate product performance.
With more than twenty years of industry immersion, we understand the real challenges facing manufacturers — from cosmetic formulators' exacting demands for volatile silicone spreadability and residue control, to synthetic leather producers' insistence on precise hydroxyl silicone reactivity and lot-to-lot consistency, to wire and cable companies' ongoing balancing act between halogen-free flame retardancy and extrusion processability.
Deep technical expertise across the full development cycle — from molecular synthesis to application-level validation.
Dedicated to silicone monomer equilibration polymerization, functional modification, and purification. Core team members bring 15+ years in siloxane synthesis with full-process capability from bench-scale to pilot production. Our controlled polymerization process for hydroxypropyl silicone oil achieves stable PDI control in the 1.40–2.50 range.
Centered on cable compound and engineering plastics applications — flame retardant synergism, antioxidant thermal stability, light stabilizer formulation optimization. Equipped with twin-screw extruders, oxygen index testers, TGA analyzers and full processing/evaluation capability.
Focused on compounding modification, dynamic vulcanization, and molding of POE, SEBS, EPDM, TPV and other thermoplastic elastomers. Team members bring deep backgrounds in automotive components and cable manufacturing, delivering complete support from grade selection to process window optimization.
In chemical manufacturing, quality means controlling subtle yet critical differences between batches.
Strict supplier qualification audits and incoming batch inspection, with full-chain traceability from production batch to supplier for key materials.
Real-time online monitoring and automated recording of reaction temperature, pressure, time, vacuum level — instant alerts on any deviation.
Each batch undergoes testing on a minimum of 6 key indicators with a certificate of analysis issued before release. All test data permanently archived.
We understand that in the materials industry, true professionalism is not about displaying an overwhelming product catalog — it is about deeply understanding each application scenario, rigorously controlling every production batch, and standing reliably behind every promise. That is why we call ourselves Cornerstone: because we commit to being the reliable foundation our customers build upon.
