What Is Isononyl Alcohol and How Is It Produced?
Two drums of isononyl alcohol can both certify above 99.5% assay and still make DINP with measurably different low-temperature flexibility. The…
What Are Phthalate Plasticizers?
A phthalate plasticizer is an ortho-phthalate diester — phthalic anhydride reacted with two alcohol chains — that dissolves physically into rigid…
Can You Mix PVC and CPVC Resins?
CPVC carries 63 to 69 percent chlorine by mass against PVC’s roughly 57 percent. That extra chlorine lifts its glass-transition temperature…
