Alveolit

Alveolit - physically crosslinked, closed cell polyolefin foams, produced in continuous sheets, vertically foamed with two identical process skins.

Density range*: 25 - 330 kg/m³
Thickness range*: 0.20 - 8 mm 
Width range*:  1000 - 2200 mm

*depending on type/grade

• thickness range between 0.20 and 8 mm (single layer). Multi-layer up to 40 mm
• excellent physical properties
• available as flame retardant type (in accordance with German DIN 4102 - B1 and B2, French M1, Italian CSE/RF3, Automotive FMVSS 302, etc.)
• choice of softness, depending on type and grade
• fine regular, closed-cell structure
• excellent thermoplastic properties, in particular vacuum and pressforming characteristics
• wide working temperature range
• excellent thermal insulation characteristics
• very good impact sound insulation properties
• low water absorption values
• very low water vapour permeability
• good weatherability
• inert to a wide range of chemicals
• no odour
• ecologically and chemically neutral
• safe disposal by recycling, dumping or incineration

Alveolit types are defined by specific characteristics and based on different formulations:

• TA*/** standard type
• TA FRZ German construction agreement (´Bauaufsichtliche Zulassung´)
• DIN 4102-B1/l= 0.040
• TA IL FRZ German construction agreement (´Bauaufsichtliche Zulassung´)
• DIN 4102-B1/l= 0.035 (improved lambda values)
• TA FRO flame retardant according French M1
• TA SAN Sanitized ", with anti-microbial properties
• TE*/** soft elastic type
• TEE*/**/*** super soft elastic type
• THL SR special lamination type
• TL, TLV*/** improved vacuumformability and toughness
• TLA special improved vacuumformability
• TLG more flexibility and improved dimensional stability
• TMA SR improved flexibility and toughness
• TME SR improved flexibility and softness
• TP FR, PP foam, fulfilling FMVSS302 with low density and reduced thickness potential
• TPO, PP foam, with improved softness including high temperature stability
• TP SMK, TP LPM, TP LPX, PP foam, especially for Low Pressure Injection Moulding (LPM) processes
• TP SPV, PP foam, especially for vacuumforming applications
• TP VX, TP VF, PP foam, especially for improved vacuumforming performance
• TT* improved dimensional stability compared with TA, TL

* also available as flame retardant type (e.g. FR, FRS, FRB)
** also available as S type (modified for adhesive coating)
*** also available as SR type (special type for adhesive coating)
