Description

LOTADER® AX8700 is a random ethylene – butyl acrylate – glycidyl methacrylate terpolymer (E-BA-GMA).
• Acrylic ester brings softness and polarity, while keeping high thermal stability during processing.
• The high content of acrylic ester leads to high flexibility (low crystallinity) and high impact absorption behaviour.
• Glycidyl methacrylate gives reactivity (versus OH, COOH and NH2 groups), leading to optimal dispersion during melt mixing with engineering thermoplastics.
• As an ethylene copolymer, LOTADER® AX8700 is compatible with LDPE in all
proportions, and with almost all other ethylene copolymers.

LOTADER® AX8700 is suitable as:
• additive to improve impact strength of engineering thermoplastics (PPS, PBT, PET) and PC/PBT, PC/PET and PC/ABS alloys
• compatibilizer for polyesters/polyolefins blends
• bitumen performance enhancer / additive for asphalt modification
• adhesion promoter onto metallic surface.

Processing

Heat stability of acrylate comonomer allows processing temperatures as high as for polyesters (PBT, PET) and PPS, which are the main material using LOTADER® AX8700 as impact modifier.
CAUTION: LOTADER® AX8700 reacts with polymers containing maleic anhydride and acid.
This reaction may generate gels or can block an extruder if not controlled. Extruders must be thoroughly purged before and after extruding LOTADER® AX8700.

Storage, Handling & Safety

LOTADER® AX8700 should be stored in a ventilated area, away from heat, humidity and direct sunlight. Improper storage conditions may cause degradation and could have consequences on physical properties of the product.
Due to its physical properties (Vicat temperature <40°C), it may be possible that the LOTADER® AX8700 shows some caking. This is particularly true during summertime.
Safety data sheet as well as information on handling and storage of the LOTADER® AX8700 are available upon request to your SK Functional Polymer representative.
