Low-density polyethylene is a light, strong flexible material with low gas and water permeability, also a good dielectric. Under certain conditions it has a high chemical resistance to organic solvents and aggressive environment. Sheets of high-density polyethylene LDPE possess low density and low stiffness (soft). LDPE sheet processing: thermo- and vacuum-molding, milling, cutting, welding, gluing. Operating temperature for LDPE sheets ranges from -40 ° C to + 70 ° C. In case of fire the sheets have technical characteristics as follows: flammability group - G4 according to GOST
* 30244; smoke-forming ability - D3 according to GOST 12.1.044; group of flammability - В2 according to GOST 30402; toxicity index - T4 according to GOST 12.1.044.
Characteristics:
- High elasticity and deformation
- High frost resistance
- High impact strength
- Low vapor and moisture permeability
- High welding strength
- High resistance to acids, alkalis and alcohols
