Benefits and features
Lotader® flexibility, heat stability, processability and adhesion versatility make it an outstanding resin as an impact modifier, coupling agent, compatibilizer, tie layer for adhesion promoter.
Adhesion – Extrusion lamination
Lotader® resins are easy to process and can bond onto many different substrates. They give outstanding performance on difficult substrate such as reverse printed films.
They are used:
As a concentrate for LDPE:
Lotader® terpolymers, such as Lotader® 4210, are used to improve LDPE adhesion to foil.
Interest: good adhesion, very short transitions to LDPE, same high processing temperature.
A versatile adhesive for all kinds of polar/non polar, fibrous/not fibrous, organic or metallic films and foils.
- Lotader 3210 or Lotader 4503, are used pure mainly for difficult substrates;
- Higher performances can be obtained with the Lotader grades containing high comonomer content.
Flexibility – Impact modifier
Lotader® terpolymers are very flexible resins. They have been used for years as impact modifiers of engineering plastics such as PA, polyester (PBT, PET, and glass fiber reinforced PET/PBT), PC/ABS, and PPS.
The epoxide functionality has been introduced in Lotader® by copolymerisation of glycidyl methacrylate (GMA) during production. Glycidyl methacrylate makes Lotader® GMA highly compatible with polyester and PPS.
Lotader® resins offer:
- good heat resistance compatibility with high process temperatures encountered in the process of polyesters and polyamides (> 250°C)
- low Tg depending on the acrylate type (EA, MA, BA) offering good impact
- Lotader® and Lotryl® wide range of acrylate content allows for tailor-made formulations and different softness degrees.
Lotader® resins can be used in high temperature processes without acid production or corrosion.
As an adhesive
Lotader® resins are used as a tie layers for the manufacture of food packaging barrier films and hot melt adhesives.
They are also used as thermoadhesive films in car interiors as well as in the formulation of hot melts for packaging and bookbindings.
As an impact modifier of engineering plastics
Lotader® resins are used in the manufacturing of PA or polyesters compounds for the electronics and automotive sectors. The use of Lotader terpolymers enable to increase the impact resistance of engineering plastics.
As a coupling agent
Lotader resins improve the mechanical properties of highly filled flame retardants compounds (HFFR) used in cable and construction industries
