Influence of Surface Migration of 6PPD as an Amine Type

Ozone resistance of vulcanized isoprene rubber containing 6PPD as an amine type antioxidant was investigated at temperatures between -30 °C and 55 °C. Both pure gum compound and carbon black filled compound were prepared by mixing isoprene rubber with zinc oxide, stearic acid, sulfur, accelerator and 6PPD.

Migration of Chemical Compounds from Packaging Polymers

This migration is influenced by several parameters, such as temperature of contact, duration of contact, surface area of contact, types of components in packaging material, and more importantly, type of foodstuff (fatty, acidic, or aqueous) (Barnes and others 2007; Veraart and Coulier 2007; Khaksar and Ghazi‐Khansari 2009).

The gum and HAF-filled Ref-0 blends also clearly show surface discoloration and staining, caused by the use of 6PPD in the compounds. The staining is more obvious in the dynamic test than in the static case, mainly because the stretch cycles of the specimens accelerate the migration of 6PPD to the surface.

Ozone Resistance - an overview | ScienceDirect Topics

Ozone resistance combined with sulfur vulcanizability was the incentive for the development of high molecular weight rubbery isobutylene–β-pinene copolymers. 65 Isobutylene/β-pinene monomer charges readily copolymerize (for example with ‘H 2 O’/EtAlCl 2 /EtCl/−50 °C to −130 °C) to give random structures containing the β-pinene moiety (2), i.e. a structural element that may be

Cell Responses to Surface and Architecture of Tissue

Material surface roughness (or topography) is another important factor influencing cell adhesion and behavior. Indeed, roughness modulates the biological response of tissues in contact with the implant. Material surface roughness has a direct influence in vitro as well as in vivo on cellular morphology, proliferation, and phenotype expression.
