10 Plasticizer Characteristics Pevalen has high calculated compatibility and low volatiltiy Name Solubility parameter (J 1/2 cm -3/2 ) PVC Weight Loss (%) (mpas, 20 C) Molecular weight (g/mol) Pevalen DOTP DINCH

11 Pevalen lower haze is a response to higher compatibility Haze 20 % Pevalen DINCH DINP DOTP

12 Pevalen higher weight flow is a response to higher compatibility Diffusion from P-PVC to U-PVC Pevalen DOTP DINCH Weight Loss, %

13 Plasticizer absorption time Pevalen TM has shortest absorption time faster dry mixing processing, hence less energy required Pevalen DINP DOTP DINCH 0:00 2:24 4:48 7:12 9:36 12:00 Time, minutes

14 Pas Brookfield viscosity 2h and 24h Pevalen yields plastisol with low initial viscosity and keeps its viscosity well over time h 24 h ,5 rpm 10 rpm 20 rpm 50 rpm 100 rpm 2,5 rpm 10 rpm 20 rpm 50 rpm 100 rpm DINP DOTP DINCH Pevalen
