Polyphenylsulphone – especially high quality engineering plastic retaining very good mechanical, electrical, and thermal characteristics under high temperatures and low loads. Chemical name – PPSU.

Polyphenylsulphone – it is transparent amber coloured plastic. It may also be produced of black colour, though its characteristics stay the same irrespective of the colour. In comparison to PSU, this plastic is chemically more impact and hydrolysis resistant, what allows assuring higher number of sterilisation cycles.

Characteristics:

• Flueless when in fire;
• Resistant to gamma and x-rays;
• Features mechanical strength, rigidity, and hardness at various temperatures;
• Sufficiently impact resistant at temperature below zero;
• Ensures stability of dimensions;
• Good electro-insulation and dielectric characteristics;
• Non-flammable;
• Easy mechanical workability;
• Formed by heat treatment;
• It may be welded;
• Good adhesive characteristics;
• Resistant to multiple sterilization;
• Very high resistance to hot water and steam;
• Chemically resistant to diluted acids and alkaline solutions, lubricants, fats, petrol, and alcohols;
• Restricted chemical resistance to solvents, ketones, aromatic hydrocarbons, esters, and benzole;
• Colour: natural (yellowish) and black.
