Introduction

Introduction

This product is unplasticized polyvinyl chloride (UPVC) nanocomposite profile containing nanoparticles. UPVC is among the widely used polymers in building construction which is the more suitable option compared to metal and wooden profiles due to features such as high durability and performance, easy formability, low thermal expansion, prevention of the energy loss and non-flammability. However, the brittleness and loss of color during exposure to UV radiation are some disadvantages of these profiles. as a solution, nanomaterials are added to the UPVC which improve the impact strength of the product.

Introduction

Rainwater pipes are used to transfer the rain and snow water from roof of the buildings. Polyvinyl chloride (PVC) is kind of useful plastics in construction and buildings. By adding lubricants, this material will become softer and more flexible than plastics. If no lubricant and plasticizer is added, UPVC is obtained. Chemical resistance of this polymer makes it interesting for a variety of industries especially pipe industry. Usage of UPVC includes sewer pipelines, water mains and potable water services, power and telecommunication cables. These pipes are supposed to have chemical and corrosion resistance, high elasticity module and toughness, long term tensile strength and abrasion resistance, but they may become brittle exposed to cold atmosphere. In addition, they tend to deform and lose their strength in high temperature conditions. These pipes have been given better properties by addition of nanoparticles.
