摘要:
A composite structure including a substrate and a fluid in contact with the substrate, wherein the substrate comprises a non-woven, a foam, or combinations thereof and is characterized by having a basis weight of 15 to 500 grams per square meter.
摘要:
Embodiments of the invention provide for polyurethane binders or adhesives that result in an increased amount of renewable resources in the final composite products while yet maintaining the quality of the composite products.
摘要:
The present invention relates to an isocyanate-terminated composition having utility in the preparation of hydrophilic polyurethanes. The isocyanate composition has an isocyanate content of less than about 15 weight percent and comprises the reaction product of an aliphatic or aromatic polyisocyanate, or mixtures thereof; with a polyol composition that contains a polyether polyol derived from a molecule containing tertiary nitrogen.
摘要:
Embodiments of the invention provide for polyurethane gels or soft elastomers which incorporate renewable resources without compromising the physical and chemical properties of the gels or soft elastomers, such as resistance to many chemicals.
摘要:
A tire filling material comprises a polyurethane or polyurethane-urea elastomer that is extended with a C1-C4 ester of one or more fatty acids. The fatty acid esters are compatible with the elastomer and with the reactive materials that are used to make the elastomer. The tire filling material is soft and has physical properties that are suitable for tire filling applications.
