Plastic screw

Welding rods are used to join plastic parts and components together by applying heat and pressure. The material used for the welding rod will depend on the type of plastic being welded.
PP (Polypropylene) welding rods are used for welding polypropylene plastic parts and components. They are known for their high strength and durability and are often used in industrial and commercial applications, such as in piping systems and containers.
PPH (Polyphenylene oxide) welding rods are used for welding PPH plastic parts and components. They have a high resistance to chemicals and high temperatures, making them suitable for use in chemical processing and petrochemical plants.
PVDF (Polyvinylidene Fluoride) welding rods are used for welding PVDF plastic parts and components. They have good chemical resistance and high temperature resistance, making them suitable for use in chemical processing, pharmaceutical production, and water treatment.
UPVC (Unplasticized Polyvinyl Chloride) welding rods are used for welding UPVC plastic parts and components. They have high strength, corrosion resistance and durability, making them suitable for use in water and sewage treatment facilities and in chemical and petrochemical plants.
CPVC (Chlorinated Polyvinyl Chloride) welding rods are used for welding CPVC plastic parts and components. They have a good temperature resistance, chemical resistance and relatively low cost. They are often used in industrial and commercial applications where these properties are required.
It's worth noting that welding of plastic parts and components requires specialized equipment and specific knowledge of the welding process. Welding rods made of different materials may have different melting points, processing temperatures and overall thermal behavior.
Glue, also known as adhesive, is a common method for joining these materials together.
CPVC glue is a type of adhesive specifically formulated to bond CPVC pipes and fittings. The glue is typically a solvent-based cement that is applied to the surfaces of the pipes and fittings that are to be joined. Once the glue is applied and the pieces are brought together, the solvent evaporates, leaving a strong bond between the parts. It is important to follow the manufacturer's instructions for proper use and handling of the glue, and to ensure that the surfaces to be joined are clean, dry and free of debris.
UPVC glue works in a similar way as CPVC glue and is also a solvent-based adhesive that is used to bond UPVC pipes and fittings. It is specially formulated to provide a strong bond between UPVC parts and also can be used for other PVC plastic.
