High-density polyethylene (HDPE)
High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. HDPE is known for its large strength-to-density ratio.HDPE is soft compared to other surface materials. That makes it great for working on soft or delicate products which may scratch against harder surfaces. HDPE is often used in laboratory environments due to its lack of porosity and resistance to many solvents. An economical alternative to other specialty surfaces.
High-quality polypropylene (PP), is a thermo-plastic synthetic material which is well suited for use in laboratories. It is resistant to most chemicals (including hydrofluoric acid), easy to clean and decontaminate, impact and crack resistant, easy to integrate with different work surface materials. The work surfaces are available either as a lined top with surrounding beading and wooden base or full PP sheet.
Polyvinyl chloride (PVC)
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.[Its structure results in PVC having excellent chemical resistance together with good mechanical properties. It is for this reason that it is used for chemical storage tanks as well as the associated valves, flanges, and piping. PVC is shown to be very resistant to acids, alkali, cooling agents and an above average resistance to organic solvents. Some solvents may only swell it or deform it but not dissolve it, but some of them, like tetrahydrofuran or acetone, may damage it. PVC also has inherently superior fire retarding properties due to its chlorine content.
