ESUN’s New Product PETG with High Toughness and Impact Strength
In Nov,2014, Esun’s newest product PETG with unbelieveble high toughness and impact strength will come
to the market. Compared to the conventional polyacrylic acid esters, its impact strength is 3-10 times stronger than the old one.Also it can be printed a variety of goods due to its wonderful
flexibility. Compared to PVC,not only it is more transparent and with good gloss, but also it is
easy to print and environment-friendly.
PETG is short of Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene terephthalate), it is a kind of transparent, an amorphous type copolyester.
PETG commonly used for copolymerization monomer 1, 4 -cyclohexane two methanol (CHDM, Cylclohexylenedimethylene), its full name is
polyethylene terephthalate -1, 4 - cyclohexane 2 methyl ester.It is made of terephthalic acid (PTA),
ethylene glycol (EG) and 1, 4 -cyclohexane two methanol (CHDM), three kinds of monomers ester exchange by the method of
polycondensation,
Compared with PET it contains 1, 4 -cyclohexane two methanol copolymerization monomer, and for PCT it contains glycol monomer.
Thus,it is very different from this two kinds of material.
Due to its outstanding thermal formability, tenacity and weatherability ,PETG is far different from
the conventional PC board and the modified acrylic board, PETG can be printed directly without pre-drying, and it can be formed quickly with low printing tempereture, above this, it has good yeild.
At the same time,it can keep the product’s toughness and prevent it yellowing. As it contains uv
absorber, it can protect the sheet from the influence of ultraviolet ligh through co-eprotective
layer.
Esun’s stuff introduce this kind of material like this: PETG is a excellent material which can
combine the strength of PLA and ABS, when it is printed,its material shrinkage rate is very small,
and it has good hydrophobic,so we can keep it with noraml space.Just due to the low shrinkage rate, it can be printed
without heated bed , and it has almost no smell in the printing process.”
Strengths of PETG:
Odorlessness;Little shrinkage (not become warped edge); Hydrophobic (avoide plugging material cause
water absorption );Outstanding toughness and high impact strength;Liquidity is good, has the very wide
range of printing; High mechanical strength and excellent flexibility;High transparency; Good gloss.
Can be recycled.
