摘要:
A multilayer fluoropolymer film comprising, in order: a first layer comprising a first polymer, the first polymer comprising at least 35 mol percent tetrafluoroethylene comonomer, at least 15 mole percent vinylidene fluoride comonomer, and at least 5 mol percent hexafluoropropylene comonomer, based on the total mol percent of the first polymer; a second layer comprising a second polymer, the second polymer comprising at least 50 mol percent vinylidene fluoride comonomer, based on the total mol percent of the second polymer; and a third layer comprising a third polymer, the third polymer comprising at least 50 mol percent methylmethacrylate comonomer, based on the total mol percent of the third polymer. The multilayer fluoroplymer films are useful for example, in multilayer film applications (e.g., traffic sign protection, commercial graphic protection, paint protection, windows, windshields, building exteriors, and photo voltaics).

The present invention relates to the field of antistatic multilayer films and in particular to articles, such as bottles or recipients, made with antistatic multilayer films. The present invention discloses an antistatic multilayer film having a first layer including an ionomer resin, a second layer including an antistatic additive blended with an ionomer resin or an ethylene acid copolymer resin, wherein the antistatic additive is a permanent antistatic additive selected from the group consisting of polyetheresteramides, and a third layer including a polyolefin resin.
摘要:
An enhanced filtration multilayer laminated fabric (10) includes an air permeable, moisture-vapor-transmissive, polytetra-fluoroethylene (ePTFE) membrane central layer (12). This central layer (12) is sandwiched between a first pair of nonwoven textile layers (14, 16) and a second pair of woven textile layers (18, 20). The laminated fabric may also feature a fire resistant application. The top textile layer (18) may also include a permanent, highly breathable and highly durable electro-static discharge feature added to the inside of the layer by laying down a carbon based printed pattern on the inside of the layer. The filtration fabric (10) may be utilized to manufacture a wearable garment that is aesthetically pleasing and comfortable to wear in all weather conditions.

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.
摘要:
A multilayer interlayer structure having a low M w /high Tg layer and a high M w layer, the interlayer having a high E' modulus and a higher Tg. The high Tg layer has a Tg of at least 50 °C and a weight average molecular weight of not more than 160,000. The high M w layer has a molecular weight greater than 160,000. The interlayer structure has increased stiffness without having to increase its thickness, and has an increased Tg to enable the structure to be used in applications that require good modulus at outdoor temperatures.
