Polypropylene (PP) offers exceptional chemical corrosion resistance, is strong, durable, and lightweight. It is compatible with both high and low temperatures and has excellent thermal insulating properties. KCH polypropylene tanks can be provided in Homopolymer Polypropylene or Copolymer Polypropylene materials. Copolymer polypropylene materials have greater impact strength, due to the addition of a small amount of polyethylene in the sheet material. KCH also offers High Temperature Polypropylene (HTPP). HTPP is optionally used to allow tank operating temperatures up to 230 degrees F.
Surface Finishing utilizes a variety of chemical substances contained in process tanks to electroplate or treat parts. Common chemicals used in Surface Finishing Processes are Nitric Acid, Chromic Acid, Hydrochloric Acid, Ammonia, Sulfuric Acid, Hydroflouric Acid, Sodium Hydroxide, and Phosphoric Acid.
KCH designs and fabricates Polypropylene Plastic Tanks to handle a wide variety of chemical process applications, including anodizing, electroplating, and cleaning lines for a diverse range of industries.
KCH is capable of fabricating Polypropylene Tanks up to 1½ inch material thickness. Tanks are equipped with vertical or horizontal structural steel girthing as required in order to reduce deflection. All KCH Polypropylene Tanks are hydro-tested by quality control before they are approved for installation.
KCH technicians utilize the latest technology in programmable extrusion welding and automated butt welding machines to fabricate polypropylene tanks. Extrusion Welding applies a thick, uniform weld to a material, eliminating the need for multiple rod passes. The rod material is pulled from a spool and extruded through an electronically heated screw chamber in the welding gun. The material becomes a fully molten strand which is applied to the weld area. The weld area is preheated with a heater mounted on the welding machine. This allows for a strong molecular bond to take place between the polypropylene rod and materials to be bonded.
