Easy tear polypropylene film contains a-nucleating agent" The a-nucleating agent is selected from the group consisting of sodium benzoate, l,3 2,4-bis-(3,4-dimethyl-ben-zylidene)-sorbitol, sodium-2,2 -methylenebis-(4,6-di-tert-butyl-phertyl)-phosphate and... 

In the sporting goods industry, considered here as in the health field, there is appreciable use of strapping tapes designed to prevent injury as well as to support injured joints or muscles. These athletic tapes, with deformable cloth backings to facilitate ease of wrapping and easy tear, must also have adhesive masses that permit facile removal. The sports industry also consumes tapes for wrapping hockey stick blades and baseball bat handles. 

As a 1.7 dtex (1.5 den) fiber, it can be spun into yams with a better strength conversion factor than other ceUulosics, aUowing rotor-spun Tencel to outperform ring-spun cotton or modal viscose. Fabrics can be made at high efficiency, and prove to have the anticipated tear and tensUe advantages over other ceUulosics. Direct, reactive, or vat dyes can be used, and easy care properties can be achieved with less resin finish than normal. Tencel could therefore be positioned as a new premium quaUty apparel ceUulosic and not simply as a long-term replacement for viscose. 

To improve the rheological properties and extend the very short working time, a simple polyester is kicluded as thinner. Mixing is easy, and dimensional change ki ak is less than 0.1% over several hours. Elastic recovery and reproduction of detail are exceUent. The elastomeric cycHc imine impression materials have a higher modulus of elasticity than the condensation siHcone or polysulfide mbbers, and are more difficult to remove from the mouth. The materials have relatively low tear strength and an equUibrium water sorption of 14% thus, polyether impression materials tear readily. Because of thek poor dimensional stabUity ki water, they should be stored ki a dry environment.

To improve the end use performance and make the processability easy, control of MW and MWD as well as the use of.more than one comonomer has been reported for LLDPE [28]. Union Carbide s high MW-LLDPE with broad MWD is a 1-hexene-based resin, and its film provides superior (about 30-50% higher) tensile strength, puncture resistance, and dart impact strength than conventional 1-hexene-based resin, but with lower tear resistance in the transverse direction. The broad MWD makes the resin processability easy on the conventional extruder. 

It is easy and safe to operate system tear-down and cleanup is also fast and safe. 

Often the closure is last to be considered. We call it a closure , and it is one of the last component processes on the filling line yet removing it is one of the first actions taken by the consumer. Thus, it might equally well be termed an opening for the very significant role it plays for the consumer. Easy access can enhance the product experience (often without the consumer even thinking about it). If the consumer cannot unscrew a cap or breaks a nail tearing open a closure, the whole experience is rained and a customer may be lost. 

It is not only the can body that has to be kept free from corrosion the easy-open end must also be protected. This end is scored through to create a locally thinned line of metal - the tear line when the can is opened. If this area of the can is subject to stress corrosion, then rapid leakage can occur. 

Murphree efficiencies are easily incorporated within simultaneous convergence algorithms (something that is not always easy, or even possible, with some tearing methods). (As an aside, note that vaporization... 

Pro-Pro- repeat is shown in Figure 9-22. Hydroxyproline units are formed by adding a hydroxyl group, -OH, to proiine after thej collagen chain is built. This reaction requires 1 vitamin C, which our bodies cannot make. Hydroxyproline is critical for collagen stability, so if we don t get enough vitamin C iii j our diet, the results can be disastrous. (You get scurvy, which initially results in loss of teeth and easy bruising, because your body can t repair the wear-and-tear of everyday life.)... 

Textile chemical auxiliary suppliers will provide suggested recipes in their product information. These recipes will contain recommendations for the appropriate catalyst and other additives that improve the performance characteristics of the easy-care and dnrable press finishes, such as softeners to improve the fabric handle and prodncts to improve tear strength (for example polyvinyl acetate, amino-modified or epoxy-functional silicones). Less decrease in degree of polymerisation (DP) rating and abrasion resistance is provided by adding water-based poly-nrethane emulsions of self crosslinking silicone elastomers. 

Elastomeric finishes are often combined with easy-care and durable press finishes. The silicones reduce abrasion, increase tearing strength (Ehnendorf testing apparatus - ASTM D1424), and crease recovery. For equal crease resistance and durable press performance the amount of cellulose crosslinking agents can be markedly reduced in these combinations. ...

Stabilized by resonance with the aromatic ring (Scheme 9.11). Hydrolysis of these side-chain halides is generally easy, especially if there is an electron-withdrawing substituent in the ring. Many are lachrymatory, contact of the vapour with moisture on the eye resulting in hydrolysis and liberation of HX. This irritates the eye and tears are produced. An industrial route to benzaldehyde from toluene involves hydrolysis of the intermediate product PhCHCl2.
