The requirement of combustion aspect of performance.But, modified PET is in engineering plastic modification field, and always one weighs difficult point.Owing to PET is half
Crystalline polymer, its crystallization rate is slow, causes its shrinkage factor big, and injection molding cycle is long, and heat distortion temperature is the highest, it is impossible to
Meet design of material requirement.In actual applications, also bring demoulding difficulty, part removal retrodeviates that soft deformation etc. is many asks
Topic.
Modified PET material crystalline is slow, the glass transition temperature Tg that main cause is PET of molding cycle length is higher (about
78 DEG C), in injection molding process, the PET melt of heat is when running into colder mold cavity, and molecular motion ability is by significantly
Suppression, causes crystallization quickly to carry out.
Solve this problem, for Shooting Technique, mould temperature need to be set in more than 90 DEG C, be beneficial to PET and crystallize, but the party
Method is higher to equipment requirements, and energy consumption is the biggest；For from modified PET formula, the nucleation capability of PET need to be improved and reduce PET's
Glass transition temperature Tg, i.e. carries out plasticising to PET.Conventional nucleator and crystallization promoter (plasticizer) have Pulvis Talci, illiteracy
De-soil, rare earth, sodium benzoate etc., crystallization promoter has Polyethylene Glycol, montanic acid, vinyl ionomer etc..Wherein, have most
Effect for sodium benzoate and Polyethylene Glycol compound system, but they efficiently come from its decomposition to PET, reduce
, in injection moulding process, there is the obvious problem of curtain coating in the glass transition temperature of PET.
