Product Overview
Small BossSmallBoss PVC Valve Compound is a high-performance rigid PVC granule specifically engineered for injection molding of PVC valves, including ball valves, check valves, butterfly valves, and diaphragm valves. With over 30 years of PVC modification expertise, our compound delivers exceptional dimensional stability, high impact resistance, and superior pressure performance for water supply, irrigation, chemical, and industrial piping systems.
Our valve-grade compound features optimized melt flow properties for smooth injection molding, excellent surface finish, and consistent wall thickness. Available in grey, white, and custom colors, it meets international standards including ISO 1452, ASTM D1784 (Cell Class 12454), and NSF-61 for potable water applications.

· Advantage
Small Boss🔶Poor Dimensional Accuracy & Valve Leakage
Precision-formulated granules ensure uniform shrinkage (0.3-0.7%) and excellent dimensional stability, passing hydrostatic pressure tests with consistent sealing performance.
🔶Low Impact Resistance & Brittle Fracture
High-impact grade compound delivers Charpy impact strength ≥5 kJ/m² with excellent toughness at low temperatures, preventing brittle fracture during installation and service.
🔶Narrow Processing Window & Surface Defects
Premium thermal stabilization ensures a wide processing window (170-200°C) with smooth melt flow, delivering glossy defect-free surfaces and reducing machine downtime.
🔶Pressure Failure & Long-Term Durability Risk
30+ years of formulation expertise guarantees consistent pressure performance — passes ISO 1167 hydrostatic test, NSF-61 potable water certification, and 10,000+ cycle fatigue testing.
🔶Proven Quality Control
Every batch undergoes rigorous QC testing including mechanical properties, dimensional stability, and color consistency. Our ISO-certified lab ensures compound performance matches specifications batch after batch.
· Application
Small Boss🔶Water Supply & Drainage Fittings
PVC thread fittings, drainage fittings, sewage pipe fittings, and fittings for water supply. Ball valves, check valves, and butterfly valves for municipal water systems, agricultural irrigation, and industrial fluid control.
🔶Joint & Connection Fittings
Cross, elbow, adaptor, tee, nipple, couplings, conduits, bushings, and reducer sockets. Thread adapters and connection components for reliable pipe joining in pressure and non-pressure applications.
🔶Electrical & Plumbing Applications
Electrical conduits, outlet boxes, electrical housings, switch boxes, junction boxes, electrical boxes, and switch cabinets. Clips and drainage fittings for electrical and plumbing installations.
🔶Construction & Special Fittings
Pipes & profiles, electrical trunking, conduit and corrugated pipes, and roof fittings. Versatile compound for construction applications requiring durability, weather resistance, and long service life.
🔶Specialty Profiles
Custom extruded profiles for specialized applications in industrial and commercial settings.
🔶Custom Formulations
Tailored compounds developed to meet specific customer requirements for hardness, color, and processing characteristics.
