Classification of Wuhan Handern plasticizers
According to compatibility, it can be divided into main plasticizer and auxiliary plasticizer. Where it has good compatibility with plastics (generally greater than 50%), it can be used alone as the main plasticizer. But it has poor compatibility with plastics, it will ooze out in excess and cannot be used alone as a plasticizer.
According to the characteristics of use, it can be divided into heat-resistant, cold-resistant, flame-retardant, and non-toxic plasticizers. Generally, people are classified by chemical structure, because the general properties of plasticizers depend on their chemical structure. www.handern.com Meltblown non-woven equipment
(1) Phthalic acid is the main plasticizer, accounting for 4/5 of the total, such as DOP, DBP, DIDP, etc. www.handern.com Meltblown non-woven equipment
(2) Fatty acid dibasic acid esters are mainly used as auxiliary plasticizers for cold resistance and used in combination with (1)
(3) Almost all phosphate esters have a flame retardant effect, but have poor cold resistance and high toxicity. www.handern.com Meltblown non-woven equipment
(4) Epoxy esters have the heat stabilizing effect of PVC and are used as auxiliary plasticizers for PVC with high weather resistance. www.handern.com Meltblown non-woven equipment
(5) "Polyesters" are mainly low-molecular-weight polyesters polycondensed with aliphatic dibasic acids and diols. They have good co-heat resistance, durability, oil resistance and water resistance, but poor compatibility and processability. To be used together with the main additive.
(6) Alkyl phenyl sulfonate has good compatibility, weather resistance, mechanical and electrical properties, but poor cold resistance, and is often used in combination with (1).
(7) Chlorine-containing plasticizers, such as chlorinated paraffin, have flame retardancy and low cost, but have poor compatibility. www.handern.com Meltblown non-woven equipment
(8) Polyesters such as pentaerythritol are heat-resistant plasticizers, and glycol fatty acid esters are plug-resistant plasticizers. Product 9) Trimellitic acid esters are excellent in heat resistance, durability, compatibility and processability, and are suitable for heat-resistant cables and other pairs. www.handern.com Meltblown non-woven equipment
