Combustion property is poor.PPO has good intensity and flame retardant property, but PPO is easy to happen brittle failure due to rigid structure.Therefore, it is necessary to
A kind of existing preferable intensity is found, keeps the material of higher toughness again, and have certain flame retardant property.
Polyphenylene sulfide (PPS, Polyphenylenesulfide) is a kind of crystal type in strand containing phenyl ring and sulphur
Polymer has good intensity, modulus, good flame retardant property and higher fatigue performance etc..But PPS structure is rigid
Property big, poor toughness, be easy to happen brittle failure during material deformation, be not suitable for as stopper material.
PCTG is a kind of transparent plastic, is a kind of armorphous copolyester, and the common comonomer of PCTG is Isosorbide-5-Nitrae-hexamethylene
Dimethanol (CHDM), full name are polyethylene terephthalate -1,4-CHDM ester.It is by terephthalic acid (TPA)
(PTA), the product of three kinds of monomer ester-interchange method polycondensations of ethylene glycol (EG) and 1,4-CHDM (CHDM), it is (poly- with PET
Ethylene glycol terephthalate) compare mostly 1,4-CHDM comonomer, with PCT (poly terephthalic acid Isosorbide-5-Nitrae-ring
Hexane diformazan alcohol ester) than more ethylene glycol comonomers, therefore, the performance and PET, PCT of PCTG differs widely.PCTG is a kind of
Non-crystalline type copolyester, with the increase of CHDM in copolymer, fusing point decline, glass transition temperature rises, crystallinity decline, most
After form amorphous polymer.
