Berry Polyvinyl Chloride (PVC) waterproof membrane is a new polymer waterproof membrane which is made from polyvinyl chloride resin, and mixed with plasticizer, filler, antioxygen, ultraviolet absorber and other auxiliaries. Hongyuan adopts automatic mixing of raw material, double-screw extruder and delicate three-roller calender equipment in the PVC membrane production. berry PVC waterproof membrane features dimensional stability and high tensile strength, being a best choice for many civil and industrial projects.Berry PVC waterproof membrane mainly falls into two categories: Homogeneous & Reinforced, each with different thickness specifications. Reinforced PVC waterproof membrane employs a fabric reinforced layer in the middle, it enhances the breaking and tear strength
Mixing automation. Apply automatic temperature control, automatic time control and automatic feed control.
Extrusion equipment uses twin screw coextrusion. Screw temperature uses computer automatic temperature control system.
Handpiece uses large width diehead extrusion equipment.
Sophisticated three-roller calender equipment. The space between equipment is controlled by automation system.
Excellent aging resistance. Service life of roofing material is over 20 years; service life of underground material is over 50 years.
Root resistant penetration, specially used on planting roofings.
Welding installation. Joints are solid and environment friendly, no pollution.
