What is PP-R Pipe?

PP-R (polypropylene random) pipe, also known as tripropylene polypropylene pipe, random copolymer polypropylene pipe, or PPR pipe, is a kind of pipe using random copolymer polypropylene as raw material. It is a high-performance plastic pipe with excellent thermoplasticity and chemical resistance. It has a wide range of applications in the fields of construction, water supply, heating, air conditioning, industrial piping, etc. PP-R pipe is suitable for various occasions such as hot and cold water transmission, home water supply systems, floor heating systems, and industrial piping.

PP-R pipe has the following main features in addition to the general plastic pipe lightweight, corrosion resistance, non-scaling, long service life, and so on:

1. Good corrosion resistance: PP-R pipe has excellent chemical resistance, able to resist the erosion of acids, alkalis, chemicals, and so on.

2. Stable high-temperature performance: PP-R pipe has high heat resistance, can withstand high-temperature environments, not easy to deform.

3. Environmentally friendly and hygienic: the raw materials of PP-R pipe have no harmful or toxic elements, hygienic and reliable, not only for hot and cold water pipelines but also for pure drinking water systems. At the same time the production, construction, and use of the process of environmental pollution, belong to the green building materials.

4. Durable and anti-aging: PP-R pipe is light in weight but has high compressive strength and impact strength, and a long service life.

5.Convenient construction: PP-R pipe can be connected by hot-melt connection, which makes the construction easy and fast, without using a lot of fittings and glue.

Although PP-R pipe has been widely used all over the world because of its excellent performance. However, in the processing engineering of PP-R pipe, there are still many processing problems to be faced.

Common Difficulties faced by PP-R pipes during processing:

The production process of PP-R pipe mainly includes extrusion, mold cooling, cutting, and other processes. Among them, extrusion is the most critical step, but also the most problematic step, PP-R pipe in the extrusion process often appears pipe surface defects, pipe internal bubbles, pipe edges have burrs and other problems.

Solutions in PP-R pipes processing:

Precise control of parameters such as temperature, speed, and pressure is required during the processing of PP-R pipe to ensure the uniformity and stability of the pipe. To solve the difficulties encountered in the extrusion process of PP-R pipe, improve the quality of the product as well as improve the processing efficiency, many manufacturers usually add PPA processing additives to improve the processing performance and surface properties.

Due to the potential harm that PFAS may cause to the environment and human health, some countries and regions have begun to restrict or ban the use of PFAS materials. In response to this ban, SILIKE has developed a PFAS-free PPA & fluorine-free PPA processing aid that is a perfect replacement for traditional fluorinated PPA processing aids and has excellent processing properties.

SILIKE’s PFAS-Free PPA&Fluorine-Free PPA: A Breakthrough in Eco-Friendly PP-R Pipe Processing

1. Improvement of melt fluidity: SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 can reduce the melt viscosity of PP-R materials, and improve its fluidity, making the extrusion process smoother.

2. Improve the surface quality of products: SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 can eliminate melt rupture and improve the surface finish of products, thus reducing pipe deformation, burrs, and other problems.

3. Saving comprehensive cost: SILIKE PFAS-free Polymer Processing Aids SILIMER 5090 can enhance the internal and external lubrication performance, improve the extrusion rate, extend the cleaning cycle of the equipment, shorten the downtime, greatly improve the production efficiency, thus reducing the cost of production.

4. Environmental protection and safety: SILIKE SILIMER series PFAS-free PPA and fluorine-free PPA masterbatch can perfectly replace the traditional fluorinated PPA processing aids, Silicone SILIMER series PPA additives are completely PFAS-free or fluorine-free, to meet the current demand for fluorine ban, it is a green and environmentally friendly processing aids.

In conclusion, the PP-R pipe is a high-quality plastic pipe suitable for many fields. During processing, the addition of  SILIKE SILIMER series PFAS-free and fluorine-free PPA masterbatch can improve the flow of PP-R pipe, reduce deformation problems, and improve the surface quality of the pipe.
