This polyester resin is produced from PTA and CHDM or NPG ( very
low quantity of PETG ) .

Is it possible to use other glycol or how is it possible to riduce
crystallization without CHDM and with same performance ?

Thanks

Johnny


Yes. Anything to disrupt the crystalline structure of the PET, e.g. DEG,

IPA and DEG are ok with 2 % , but crystallization is still very high .
To eliminate crystallization ( clear ,never completely)it's necessary
20/30% IPA or more and the performances are very low.

Don't know commercial status of this patent but worth considering:
