Planetary kneader VK series

verticalbottom-entrybatch

Overview
JCT’s vertical kneader, specifically engineered for silicone resin composites, features powerful planetary mixing and a precision bottom-scraping design. It effectively solves the challenges associated with kneading high-viscosity, temperature-sensitive, and shaft-clinging materials. The system ensures thorough mixing with no dead zones and clean discharge, facilitating highly efficient production.

Key capabilities

• Operating mode: Planetary type (zero dead zones)
• Viscosity handling: 800,000 cP to 20,000,000 cP
• Temperature control range: ambient (or 0) to 220℃
• Vacuum capability: 0 to -0.098 MPa (ultra-high vacuum performance described below)
• Available scales: Laboratory, pilot-scale, production-scale

Product details
Silicone-based composites are composite materials that utilize silicone resin as the matrix and incorporate fillers or fibers (or fiber fabrics) for reinforcement. They possess the inherent characteristics of silicone resins while also exhibiting the excellent properties associated with other composite materials. Key product series include optically transparent composites, porous materials, soft magnetic composites, coatings and adhesives, thermally and electrically conductive composites, high-temperature and high-strength composites, and specialized materials for aerospace applications.
