Description
This Polypropylene Homopolymer sheet is lightweight and food compliant, ideal for various applications including chemical tanks and medical equipment construction.
Material Properties
The Polypropylene Homopolymer (PPH) sheet is characterized by its lightweight nature with a specific gravity of 0.91. It offers enhanced chemical resistance and stiffness, along with a higher working temperature range of 0°C to +100°C compared to its counterpart, the Polypropylene Copolymer (PPC). PPH also features low water absorption and excellent weldability.
Advantages and Disadvantages
One of the main advantages of Polypropylene Sheet is its excellent acid and chemical resistance, making it suitable for various industrial applications. It is also cost-effective and has high impact resistance. However, it can be challenging to machine due to its low melting point of 130°C, and bonding may require specialist processes. Additionally, it has a poor fire rating, which limits its use in certain cladding applications.
Applications
Polypropylene Homopolymer sheets are versatile and used in several applications including chemical tanks, water applications, medical equipment construction, and industrial chopping boards. They are also suitable for some cladding applications and prosthetic components.
