Embedded thermochromic pigments address problems associated with determining whether an electrically heated mat is operating properly. At least a portion of the mat, or an attachment, includes a thermochromic pigment, such that when the mat is properly activated, the entire mat, or a region of the mat, changes color, hue or intensity, giving a visual indication as to heating status. The thermochromic pigment may change the color at a predetermined temperature associated with animal husbandry such as 80 Deg. F in conjunction with a farrowing application. One or both of the upper and lower layers of the mat may be constructed of plastic such as high-density polyethylene (HDPE), and the thermochromic pigment may be added to the plastic prior to molding the mat. Alternatively, the thermochromic pigment may be contained in a label or patch affixed to the mat material through a mold labeling process.

An internal tube for tanks, particularly fuel tanks of automobiles, wherein the tube has a fluid channel and a tube wall that encloses the fluid channel, wherein the tube wall has a multilayer design and is composed of at least three layers, with one inner layer based on at least one polyolefin being provided, with at least one central layer based on at least one polyamide being present, and with one outer layer based on at least one polyolefin being provided.

There is also provided a process for manufacturing the laminate for vignette and tonal image printing.

A chaff resistant and economically recyclable dunnage tray is disclosed. In one aspect, the dunnage tray includes a base portion formed from a first material and a top portion formed from a second material. The top portion is secured to the base portion, and defines at least one cavity or recess for supporting a machine component. The first and second materials are high density polyethylene (HDPE) materials with the second material including polyethylene elastomers, or plastomers. In one example, the dunnage tray is formed by thermoforming a co-extruded sheet including a first layer corresponding to the bottom structural portion and a second layer corresponding to the elastomer or plastomer portion. In one example, the dunnage tray is formed by thermoforming an extruded sheet to form the base portion and by attaching separately formed top portions with polyethylene elastomers, or plastomers to the thermoformed base portion. This invention provides solutions to chaffing or chipping of polyethylene dunnage trays, control of coefficient of friction and softness to minimize parts from sliding/abrading dunnage surfaces, and eliminates requirements for disassembly of dunnage trays and separation of materials prior to recycling.
