Flexible gloves

A heated mold is dipped into liquid plastisol (Figure 2.43a) and then drawn at a given rate. The solidified plastisol (with mold) is then cured in an oven at 350°F-400°F (176°C-204°C). After a cools, the plastic is stripped from the mold. Items with intricate shapes such as transparent ladies overshoes, flexible gloves,... 

Di-n-octylphthalate (DnOP) is used primarily to produce flexible plastics. Diisononyl phthalate (DiNP) is actually a mixture of phthalates with branched alkyl side chains of varying length (C8, C9, and CIO). DiNP is primarily used (more than 95%) to produce flexible plastics and has been used to replace DEHP in some plastics. DiNP is now widely used in products such as children s toys, flooring, gloves, drinking straws, and garden hoses. The remaining 5% of DiNP is... 

The modular system, Ecoflex and Ecovio , also fulfill aU the requirements for the production of other flexible film applications like adhesive tapes or disposable gloves, because the ratio of stiffness/flexibihty can be adjusted by the Ecoflex content. All Ecovio -Ecoflex combinations can be reduced in film thicknesses down to <10 pm. 

The CPA or "Snake Pen" consists of a pen body containing a porous wick, such as that used in felt pens, and a solution ofDMSO and any number of toxins. When the wick is touched to the victim s skin he receives a fatal dose of poison. The CPA is built from a correction fluid pen, available at any office supply store. These pens have a soft, flexible body and are easy to modify. Unscrew the top from the son pen body, squeeze out the correction fluid and flush the interior with solvent to remove all traces of its original contents. Note that most of these pens have a left-hand thread on the body. The tip of the pen is sawed off and the valve stem carefully removed. Ream out the pen tip to fit the wick. A felt tip marker pen works well as a wick, after being soaked and rinsed in sol vent to remove traces of ink. It may be necessary to trim the wick to fit. Press the wick into the pen tip until about 3/8 " protrudes and seal around it with silicone sealer. When the sealant is dry, put on rubber gloves and, using a hypodermic syringes, inject the DMSO solution into the pen barrel until it is about 3/ 4 full. Be sure not to squeeze the pen while accomplishing this. Coat the barrel threads with a little silicone sealer, screw on the cap and allow the pen to dry in a vertical position. Line the inside of the cap... 

Ethylene copolymers with methyl methacrylate and ethyl, butyl, and methyl acrylates are similar to EVA products but have improved thermal stability during extrusion and increased low-temperature flexibility. The commercial products generally contain 15-30% of the acrylate or methacrylate comonomer. Applications include medical packaging, disposable gloves, hose, tubing, gaskets, cable insulation, and squeeze toys. 

Leaking Cylinder. Wear neoprene gloves and self-contained respirator. Transfer the cylinder to a fume hood. Attach a long piece of flexible tubing to the cylinder valve outlet. Adjust the valve to give a moderate flow of diborane. Introduce the gas to the bottom of a tall vessel containing water. Diborane is hydrolyzed by water to hydrogen and boric acid.12... 

Dip Molding. Instead of a heated product, a heated male mold is dip-coated in the same way. In this case, the final flexible vinyl product is stripped off of the mold. A typical product is medical gloves. 

This substance has extensive lipid solubility and is absorbed immediately by the skin. Additionally, DMM is able to penetrate many materials including plastic and rubber compounds such as latex, polyvinyl chloride, and neoprene in a matter of seconds. In permeability tests, a Silver Shield glove of a flexible, plastic-laminate, offered skin protection from DMM for 4h. This chemically resistant glove, when worn under an outer glove that is resistant to abrasion and tears, may provide limited protection for direct handling of DMM. 

ATBC is used as a plasticizer for flexible films made of vinylchloride-vinylidene chloride copolymer and cellulose. It is used as a plasticizer in food contact applications and in vinyl toys for children (low toxicity). ATBC provides adherence to metals, low volatility, and resistance to yellowing. Also used in ink formulations, vinyl gloves, a non-VOC solvent in nitrocellulose propellants, a plasticizer in nail polishes, adhesives and coatings, and for coating both paperboard and foil. 

Ethylene-ethyl acrylate copolymers can produce very tough flexible materials and can vary from very rubbering low temperature melting products to polyethylene-like materials. EEA is used as a hot melt adhesive, for disposable gloves, tubing and sheeting.
