Product Description Customized CPP Film Grade Resin for Various Packaging Solutions - Factory DirectChlorinated Polypropylene (CPP) Resin is a chemically modified plastic. It's made by treating polypropylene with chlorine gas. This process gives it special properties that regular polypropylene doesn't have.It has excellent adhesion to various materials, especially plastics like polyethylene and polypropylene itself. This makes it a key ingredient in adhesives, inks, and coatings. For example, it's widely used in plastic packaging to help inks stick to polypropylene surfaces.It's also known for its good resistance to water, heat, and chemicals.In short, CPP resin is a vital material that helps make inks and paints stick better to difficult plastic surfaces.

FAQQ1: What is Chlorinated Polypropylene (CPP) Resin?A: Chlorinated Polypropylene (CPP) Resin is a modified thermoplastic created by introducing chlorine atoms into the polypropylene polymer chain through a chemical reaction. This process significantly enhances its adhesion properties, solubility, and compatibility with other materials compared to standard polypropylene.Q2: What are the key properties and advantages of CPP Resin?A: CPP Resin offers several advantages:Excellent Adhesion: It adheres strongly to difficult-to-bond substrates like polyolefins (PP, PE), metals, and plastics.Good Solubility: It is soluble in a wide range of organic solvents, making it ideal for formulating liquid coatings and inks.Chemical Resistance: It offers good resistance to water, acids, and alkalis.Flexibility: The chlorination process improves the flexibility of the base polypropylene.Q3: What are the main applications of CPP Resin?A: Its primary applications are in industries requiring strong adhesion:Adhesives: Used in plastic bonding, especially for automotive interiors and consumer goods.Inks: Acts as a key binder in flexographic and gravure printing inks for polypropylene films (BOPP) used in food packaging.Coatings: Used as a primer or tie-layer coating to promote paint adhesion on polyolefin parts in the automotive and appliance industries.Modifying Agent: Used to improve the properties of other materials, like certain paints and resins.Q4: How is CPP Resin different from standard Polypropylene?A: While standard polypropylene is non-polar and has very poor adhesion properties, CPP resin is polar due to the chlorine atoms. This polarity is what gives CPP its exceptional adhesion and solubility, which unmodified polypropylene lacks.Q5: What is the typical Chlorine Content in CPP Resin?A: The chlorine content can vary depending on the desired application and properties. It typically ranges from 20% to 40%. A lower chlorine content offers better compatibility with hydrocarbons, while a higher content improves solubility in polar solvents.Q6: What is the form and packaging of your CPP Resin?A: Our CPP Resin is typically supplied in the form of white or light-yellow granules or powder. It is commonly packaged in 25 kg multi-layer paper bags or 600-1000 kg jumbo bags to ensure moisture protection and safe transportation.Q7: How should CPP Resin be stored?A: It should be stored in a cool, dry, and well-ventilated place away from direct sunlight and heat sources. Keep the containers tightly sealed when not in use to prevent moisture absorption and contamination.Q8: Is Chlorinated Polypropylene Resin safe?A: When handled properly according to the provided Safety Data Sheet (SDS), it is generally safe. However, as with many chemical products, appropriate safety measures should be taken. Avoid inhalation of dust and contact with eyes and skin. Always refer to the specific SDS for detailed safety and handling instructions.Q9: Can you provide custom specifications?A: Yes, we can provide customized CPP Resin tailored to your specific needs. This includes adjusting parameters like chlorine content, viscosity, and solubility to meet the requirements of your unique application. Please contact our sales team to discuss your customization options.Q10: What is your MOQ (Minimum Order Quantity) and lead time?A: Our standard MOQ is typically one 20-foot container, but we may accept smaller orders for trial purposes. The production lead time is usually 15-20 days after order confirmation, depending on the order quantity and specific requirements.
