Normally, elastomers are bonded to rigid substrates during vulcanization. But sometimes, there are advantages to bonding after the rubber article has already been cured. For instance, post vulcanization (PV) bonding makes sense when assemblies contain large, complex inserts that cannot be practically handled in the press. Vulcanization bonding requires lower temperatures and longer times to achieve the highest quality. On the other hand, injection molding processes favor highly eff...

Surface rearrangement of tailored polyurethane-based coatings.
JCT Research ; Polyurethane coatings with different network composition were prepared from an oligomeric diol, a diisocyanate, and a low molecular weight triol. The glass transition temperature of the network was tuned by the ratio of diol and triol and the composition (aromatic or aliphatic) of the diisocyanate.
The effect of surface energy of boron nitride on polymer processability.
Polymer Engineering and Science ; INTRODUCTION Although the development of catalysts such as metallocenes has made the synthesis of polyolefins easier and improved their mechanical properties, the processing of these improved polyolefins has become more challenging for manufacturing of finished products of high surface quality.
Relationship between surface chemistry and surface energy of different shape pigment blend coatings.
JCT Research ; Introduction The first few atomic layers play a major role in determining the performance of many coating processes. Many processes such as printing (1,2) and adhesion (3) depend on the properties of the surface and, in particular, its surface energy. Surface chemistry and surface energy should be
Effect of Surface Modification of High-Density Polyethylene by Direct Current and Radio Frequency Glow Discharge on Wetting and Adhesion Characteristics
Metallurgical and Materials Transactions ; The present investigation aims to optimize the process parameters of Direct Current (DC) and Radio Frequency (RF) glow discharge treatment through air in terms of discharge power and time of exposure for the surface modification of high-density polyethylene (HDPE) sheet, for attaining best adhesive
Surface energy characterization of preservative-treated wood and E-glass/phenolic composites.
Forest Products Journal ; Abstract The effects of various wood preservative systems and treatment processes on the surface energy of wood and E-glass/phenolic pultruded composite material for wood reinforcement were characterized using surface energy methods.

Bonding low surface energy plastics.(Brief Article)
Machine Design ; Adhesion is a surface phenomenon. A surface's texture, porosity, and flexibility affect the adhesive strength of a plastic joint. Ditto for any contaminants such as mold release agents, plasticizers, or other resin formulations that migrate to the surface. Surface energy also influences adhesion.
Factors Regulating Cheese Shreddability
Journal of Dairy Science ; ABSTRACT Two sets of cheeses were evaluated to determine factors that affect shred quality. The first set of cheeses was made up of 3 commercial cheeses, Monterey Jack, Mozzarella, and process. The second set of cheeses was made up of 3 Mozzarella cheeses with varying levels of protein and fat at a
Gross melt fracture elimination: the role of surface energy of boron nitride powders.(Abstract)
Polymer Engineering and Science ; INTRODUCTION It is known that the rate of production of many commercial polymer processing operations, such as extrusion, blow molding, film blowing and various coating flows, is limited by the onset of flow instabilities (1-4). These instabilities manifest themselves as distortions on the surface
Energetic surface treatments: advanced methods increase surface energy and properties.(NORTH AMERICA)
Plastics Engineering ; Additional processing steps are sometimes required for enhancing a material's surface properties. For example, nonpolar materials such as polyolefins have low surface energy and reactivity, which means they may require surface treatments to adhere to inks and coatings. Promoting adhesion is made
