Pvc Glove Plasticizer

REPORT

1.Product Introduction

This eco-friendly plasticizer JD81 is based from natural plant oil. It is produced through specific process of purifying linseed oil derivatives and saturating unsaturated bonds which may affect intermiscibility and stability. Therefore this light color product is better soluble with PVC than DOTP,DINP and have high plasticizing efficiency, mechanical property, processability, stain resistance property, cold resistance property and weather resistance property.

Analysis result:

a、Viscosity of JD81 is much lower and easily to disperse

b、It is helpful to produce low-weight glove due to JD8’s low density   

c、Better plasticating effect due to low molecular weight 

d、The heating lose of JD81 will higher due to low flashing point

We can understand from above form,the lowest viscosity of formula A (JD81) is 615 map.s after 4 hours, and viscosity increase to 2500+ map.s after 16 hours.the lowest viscosity of formula B (DINP) is 617 map.s in the first beginning,and increase slowly as time goes

We can understand from above form that formula A (JD81) is more sensitive to the temperature, the viscosity increased to 4000 mpa.s when temperature is 54℃。 And the variation trend of viscosity for formula B (DINP) increased step by step,easier to be controlled
