摘要:
Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one Rl balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

Multilayered interlayers having good acoustic properties comprising a stiff skin layer(s) and a soft core layer(s) are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer) comprising plasticized poly(vinyl acetal) resin; a second polymer layer (core layer) comprising plasticized poly(vinyl acetal) resin; wherein at least one plasticizer is a high refractive index plasticizer. The multilayered interlayers have low mottle and resist mottle formation.
摘要:
Composite laminate interlayers for a glass laminate comprising a sheet of polyethylene terephthalate (PET) layer (203) between layers of plasticized polyvinyl butyral (PVB) adhesive layers (202, 204), wherein at least one of the PVB adhesive layers is stiffened, e.g. by reduction in the amount of plasticizer, and has a glass transition temperature greater than 35 °C. The PET is preferably 0.075 to 0.25 mm (3-10 mils) thick and can have a functional coating (407) for reducing radiation, e.g. UV or IR or visible light, transmission through the glass laminate. The laminate can also comprise at least one elastomeric layer (406) adapted to reducing sound transmission through the glass laminate. The laminates exhibit enhanced maximum flexural modulus of greater than about 350 Newtons/centimeter.

A polymer interlayer comprising a layer comprising a poly(vinyl acetal) resin having a residual hydroxyl content and a residual acetate content, and a plasticizer, wherein the residual hydroxyl content, the residual acetate content and the plasticizer are selected such that the polymer interlayer has at least one glass transition temperature less than about 20° C. and a peak tan delta of greater than 1.33, and a glass panel having a configuration of 2.3-mm glass//interlayer//2.3-mm glass and at 20° C. has a transmission loss, TLw, of greater than 42 decibels as measured by weighted average sound transmission loss at 2000 to 8000 Hz, and a transmission loss, TLc, of greater than 38 decibels at the coincident frequency is disclosed.
摘要:
A process for producing a multilayer glass laminate panel having two glass sheets with a poly(vinyl butyral) interlayer sandwiched therebetween, the process comprising the steps of: providing two glass sheets; providing a poly(vinyl butyral) interlayer, and inserting the interlayer between the two glass sheets to produce a laminate; removing air from the produced laminate; applying heat and pressure to the laminate for a hold time, wherein the laminate is free of bubbles at the edges of the laminate. The multilayer glass laminate panel has improved optical properties, and specifically reduced levels of edge defects, such as edge bubbles in the laminate.
