A thermoplastic polymer advanceable by solid state polymerization is blended with at least one dissimilar thermoplastic polymer. The blend is solid state polymerized to provide a modified polymer alloy blend having at least one physical or chemical property different from that of the blend before solid state polymerization. The modified polymer alloy blend may be coextruded with a layer of thermoplastic extrusion polymer having a melt viscosity similar to that of the modified polymer alloy.

A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.

An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet, including coextrusion processes are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet of the invention is disclosed. The backsheet of the instant invention may comprise an exterior layer having inner and outer surfaces, a middle layer, having inner and outer surfaces, and an interior layer having inner and outer surfaces. In one embodiment of the invention, the outer surface of the middle layer may be adjoined to the inner surface of the exterior layer, and the inner surface of the middle layer may be adjoined to the outer surface of the interior layer. The exterior layer, middle layer, and interior layer may be adjoined via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together. The backsheet of the invention improves upon the efficiency, strength, weather resistance, cost, and useful life of the solar panels in which the backsheet is incorporated.

The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection infrared range of the electromagnetic spectrum reduce heating by sunlight in the near infrared dark tinting in the visible range. Low density conductivity are obtained inter alia by inserting in the near in order to area despite and low heat light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.

The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.

An erosion resistant article such as rotor blades for helicopters and wind turbines having the leading edge surface protected from damage from high speed impingement of rain or sand with a protective coating formed from specific polyurethane or polyurea coating having a defined set of minimum physical properties where the protective coating can be applied as a liquid coating and cured in place or as a preformed complementary shaped covering to protect the leading edge against erosion damage in service.
