WebA recommended minimum temperature of 150°C (302"F) is normally utilized, and as the temperature is increased to a maximum of 210°C (410°F), the molding time is reduced. Typical molding temperatures are between 175°C - 200°C (347°F - 392°F), The autoclave cure is similaly affected by the time/temperature relationship Normal autoclave cure … WebThe Ts2 value is measured in time units and indicates when the compound starts to vulcanize. The closer we approach the finally crosslinked compound, the higher is the …
WebThe calculation returns the slope of the linear regression line of the log (torque) versus log (time) plot over a specified time interval after stopping the rotor at the end of a Mooney viscosity measurement. According to ISO Standard the regression is calculated between 1.6 and 5 seconds from rotor stop. UNIT: Mu/sec. Webcrosslinking density. The scorch time (t s2) is a measure of the time at which vulcanization of the mixes begins. Tables 4.1 and 4.2 illustrate that NBR with 6PPD antioxidant (NC), …

Scorch time is usually shortened when co-agents are used; that can result sometimes a disadvantage, since scorch safety is worsened. Peroxide vulcanisation leads to a rubber network in which the polymer chains are linked to each other by very stable covalent carbon-carbon bonds. is selectively permeable
