Description

For the sake of a more efficient chemical action, the anti-aging additive is required to be mutually soluble and dispersive in polymers and also to have sustained effectiveness.<BR>Twelve kinds of commercial anti-aging additives to natural rubber have been investigated for their volatility. The results show that anti-aging additives with a lower melting point are more volatile. Volatile additives are found effective against dynamic fatigue (bending crack), but not so against thermal deterioration; additives of phenol system cannot be expected to be effective against either.
