Performance features
StoPac is a textile-reinforced rubber blanket specially designed to reduce surface cracking in operation. Cracking is the largest single problem in using extensible blankets and this new material has significantly improved cut and tear resistance. It has good releasing properties, withstands high pressure and continuous flexing in operation.

In operation the blanket may display slightly different characteristics in start-up and grinding. It performs as if slightly softer.

Dimension	Type Inside circumference Max. face width 1 7620 mm (8' ID) 9000 mm 2 5745 mm(6' ID) 6000 mm 3 4785 mm (5' ID) 4000 mm
Colour	Brown.
Hardness	55±5° Shore A.
Linear load	Optimal Nip bar pressure 20-25 kN/m. Max. 30 kN/m.
Tension	Optimal 5-6 kN/m. Max. 7 kN/m.
Temperature	Max. Drying Cylinder temperature is 115°C (240°F).
Thickness	The standard thickness is 25.4 mm (1"). Optional 28.5 mm (11/8").
Shower water temperature	Max. 20°C (70°F).
Resistance	StoPac has good resistance to the normal chemical components of sack paper pulp. Substances to which the material is not resistant include turpentine and chlorinated solvents. Blankets should be ground every 24 hours of operation. Edge showers must operate continuously to avoid edge cracking. Outside shower must operate automatically in case of paper break. Inside showers must run continuously to cool and lubricate nip.
Operating criteria	Grinding: Initial grinding. Use 40-grit grinding belt. Pitch equal to grinding belt width. Daily grinding. Use 60-grit grinding belt. Pitch 0.5 x grinding belt width. Positioning of grinder according to existing equipment. At shutdown: Offload nip pressure. Reduce tension. Rotate blanket occasionally.
