The HPL partition wall for cleanroom is a structure with a thickness of 45mm, made of 2 x 4 mm thick external HPL panels and internal insulation, which vary according to the project requirements..
Each panel made by Easypharma is completely sealed on all 4 sides, using extruded aluminium profiles, designed to create the structure and complete closure of the internal insulation.
Easypharma supplies different types of insulation: rock wool (RW), polystyrene (EPS), aluminium honeycomb (HC), polyurethane (PUR), polyisocyanurate (PIR).
In all cases, the densities of such insulations are extremely high, so as to guarantee superior mechanical stability of the wall itself
What is HPL for Cleanroom
The HPL surfaces are distinguished by some highly technical features, namely:
High mechanical resistance to impact, total resistance to water, chemical detergents, steam, impact and highly resistant to abrasion.
Over 40 layers of kraft impregnated with melamine and phenolic resin. The 4 mm thick HPL panel has a transparent finish on both external sides that protects the decorative layer below. Solid, structured, unpainted material (the colour is part of the material). Antistatic and antibacterial given the nature of the product itself, HPL is used extensively in controlled contamination environments.
The central dark brown layer consists of a series of kraft papers impregnated with phenolic resins, pressed to 9 MPa at 150°C. A protective PVC coating protects the panel during the production, transportation and installation phases. We chose to use HPL-grade products only when realising our cleanrooms, in accordance with standard EN438.
