Colour Masterbatch for Fittings

Formulating the Right Masterbatch for Pipes & Fittings

Plastic pipes can be categorized into two types viz the general purpose non-pressure that includes corrugated drainage and conduit pipes. The other is the pressure pipes that are mainly used for transportation of water and fuel gas. The best pipes are made with fractional melt flow or with low melt virgin polyolefin resins. Adding black masterbatch can improve the mechanical properties of the pipe, making it more flexible while offering UV resistance to prolong the service life of the pipes and fittings.

Manufacturing Elements of Pipes & Fittings: 

• The let down resins consisting of performance additives

• The carrier resins in masterbatch (typically LDPE, LLD, or MLDPE)

• The type of pigment used in the masterbatch 

• The dispersion of ingredients 

Colour masterbatches are extensively used in the manufacturing process of extruding pipes and extruding bars like gas pipes, tap-water pipes, and fittings. Additives protect and stabilize pipes for long-term performance and integrity while protecting against ESCR (environmental stress cracking), slow crack growth, and pressure.

Masterbatches for Different Types of Pipes & Fittings 

• High-Density Polyethylene (HPDE Pipes): A Versatile Solution for Many Industries many industries use HDPE pipes to transport water, gas, chemicals, and other fluids for their superior strength, flexibility, and resilience. HDPE fittings perform exceptionally in tough conditions and durability.

• Low-Density Polyethylene (LDPE Pipes): These flexible thermoplastic pipes are popular for their low weight and flexibility. With ease of installation and resistance to climatic conditions, LDPE fittings are used in different applications, especially in low-pressure systems and irrigation. 

• Polyvinyl Chloride (PVC):  PVC fittings are used in different sectors for their affordability, durability, and flexibility. They have high resistance to corrosion, chemicals, and enviromental conditions. 

• Double Wall Corrugated (DWC Pipes): DWC pipes are distinguished for high strength and resilience, making them ideal for underground cabling, sewage systems and drainage. 

Liquid Masterbatches for Fittings & Pipes 

Liquid masterbatches have become popular for fittings and pipes for their accuracy in colour matching and excellent dispersion properties. These MBs provide uniform colouration and improve the aesthetics and functional properties of fittings and pipes. Liquid masterbatches ensure consistent colours across the end product, reducing streaks and uneven tones. They need lower pigment loading, saving costs while imparting vivid colours. The superior flow properties lead to faster production cycles and better surface finishes that are essential in fittings and pipes. 

Common Specific Colours in Fittings

Certain colours are industry standards for fittings and pipes in terms of functionality, aesthetics and compliance with standards. 

• Grey: This is a neutral colour, non-reflective, and especially used for its durability and resistance. It is commonly used in plumbing systems, HVAC systems, electrical conduits, and industrial piping.

• White: White liquid masterbatches are commonly used in water supply pipes and fittings, including household plumbing systems, hot & cold pipes, and drainage systems. 

• Ivory: Ivory offers a more premium & sophisticated look while maintaining resistance to fading or yellowing over a period of time. It is commonly used in high-end fittings, decorative piping, and visible installations. 

• Black: Jet black masterbatches are commonly used for outdoor fittings and pipes, especially for industrial drainage. It offers excellent UV protection and minimizes the visibility of scratches and stains for long-term performance. 

Noise Reduction Masterbatch for Fittings & Pipes 

For noise reduction pipes and fittings are designed in a three-layer structure. The outer layer is made of impact resistance PP (polypropylene), the inner layer is made of wear resistance and chemical resistance propylene, and the outer-most layer is made of reinforced polypropylene that serves as sound-absorbing. The noise reduction masterbatch consists of nanoparticles that increase the elastic modulus, yield strength, and impact resistance. 

Wide Range of Colour Masterbatches for Fitting, Pipes & Hoses 

PCPPL, a leading master batch company in India, is your trusted partner in the pipes and fitting industry. Our comprehensive range of colour masterbatches, designed specifically for this sector, is non-toxic and exhibits excellent weather and heat resistance. They have exceptional uniform dispersivity and compatibility. When formulating masterbatches for high-performance pipes and fittings, we use high-quality virgin material to meet stringent quality standards. 

Additive Masterbatches for High-Performance Pipes & Fittings 

Additive masterbatches are used to enhance the functionality of plastic fittings, adding mechanical properties and imparting specific characteristics. Plastic fittings and pipes are subject to pressure and stress while carrying fluids. Incorporating additives like UV masterbatches protects the pipes and fitting from prolonged sun exposure, natural wear and tear, and extreme weather conditions. Additive masterbatches enhance the overall quality and structural integrity of the fittings. While also improving creep resistance and impact strength of fittings, pipes, and hoses.
