History and Development
SILIKE was established in 2004 as a technology-oriented enterprise dedicated to silicone applications in plastics. Over time, the company expanded from general silicone-plastic additive development into more specialized product families for slip, anti-blocking, anti-abrasion, anti-scratch, and anti-squeaking performance modification.
A major development milestone was the company’s move into footwear and film-processing solutions, where it introduced anti-abrasion formulations for soles and slip/anti-blocking masterbatches for plastic films and packaging. These product lines reflect the company’s focus on solving processing and surface-performance problems that arise in thermoplastics manufacturing.
A second key milestone was the development of Si-TPV in 2020, described by the company as a new silicone-plastic combination material created through long-term research in silicone-polymer compatibility. A third milestone has been the company’s broader commercialization and export growth, with its products reported to serve customers across Asia, Europe, the Americas, and other regions.
Business Operations and Segments
The company is organized around the design and manufacture of functional additives and specialty elastomeric materials for polymer processing. Its business activity is concentrated in the plastics and rubber sectors rather than in commodity polymer production.
Its main operating themes include:
- Processing additives for improving extrusion, molding, and surface performance
- Silicone masterbatch and silicone powder products for thermoplastics
- Wear-, scratch-, and squeak-control materials for durable plastic parts
- Slip and anti-blocking masterbatches for film and packaging applications
- Si-TPV materials for softer-touch and elastomeric performance requirements
The company states that it collaborates with universities and research institutes such as Sichuan University, Nantong University, Xihua University, and several chemical research organizations, indicating a business model that combines formulation development with application support.
Products and Technologies
SILIKE’s product range centers on silicone-modified polymer additives and related compounding technologies. Public materials identify several named product families, including:
- Silicone Masterbatch LYSI Series
- Anti-scratch Masterbatch
- Anti-wear Masterbatch
- Silicone Powder
- Anti-squeaking Masterbatch
