ACRYLONITRILE-BUTADIENE-STYRENE (ABS)
LASTILAC compounds are based on ABS, which is a mixing of Acrylonitrile, Butadiene and Styrene. - Acrylonitrile provides thermal stability and chemical resistance;
- Butadiene provides toughness, overall at low temperature;
- Styrene provides brightness and mouldability.
Main properties - Excellent impact resistance, even at low temperature;
- Low shrinkage levels;
- Excellent dimensional stability;
- Excellent surface aspect;
- Good soundproofing.
Notes
LASTILAC compounds are tougher and stronger than LASTIL grades.
Reinforced grades
Glass fibres reinforced versions provide high stiffness while maintaining an excellent dimensional stability.
Flame-retardant grades
An excellent mouldability and surface aspect characterize the flame-retardant versions. In order to improve the surface appearance of the glass reinforced products mould surface should be polished. Usually, flame-retardant versions offer poor UV resistance.
Blends
In order to further improve flexibility in material use, blends obtained by mixing ABS with other base resins have been formulated. See LATIBLEND family.
Electrically anti-static / partially conductive / dissipative grades
Family compounds can be formulated with anti-static, partially conductive or dissipative properties, even in reinforced versions: search grades in LATISTAT and LATIOHM product range.
E.M.I. shielding grades
Check LATISHIELD family for more information about products with E.M.I. shielding properties.
Moulding
Cracking or long-term rupture due to internal residual stresses can be found. In order to prevent or reduce such phenomena, careful part design and correct moulding process are required. Eventually, annealing parts at 80-90°C (1 hour per mm of wall thickness) allows reducing residual stresses. |
