Together they provide the durability fo the hair spray film, the film strength and the elasticity to withstand movement without film failure.
It is well known that the MAC's possess superior film strength and adhesion to metal surfaces when compared to PFPE's so we would expect low particle generation as the probability of particles being shed to the air would be lower.
Intended for use in high-speed, high-pressure, high output piston, vane and gear pumps operating under severe conditions where high levels of anti-wear, film strength and temperature protection are needed.
In addition, the lubricant also helps reduce the cost of replacing parts and lost production time due to its anti-wear protection and high film strength which eliminates deposits formation and tool sticking.
Thus, it was seen as important to extend the amount of binder used to levels above that level, and determine the resulting film strength. The results of such experiments are shown in Fig.
Processors of LLDPE blown films generally add a percentage of LDPE to improve melt strength, bubble stability, and gauge uniformity, even though it may compromise film strength and toughness.
has developed lubrication technology that can be demonstrated to be over 50 times greater film strength than conventional lubricants.
And it contains additives to improve film strength when the oil is hot.
* Exceptional shear stability--Maintains effective viscosity and film strength for better wear protection during severe operation.
Figure 4 shows a linear correlation between film strength and the square root of modulus of elasticity ([R.sup.2] = 0.859).
Further increase of the number of cycles is not followed by the increase in film strength, contrary even some decrease can be observed, especially when higher loads are applied.
The 20-inch stretch film is elongated through a powered prestretch film carriage for a stretch ratio of 200% to maximize film strength and decrease film usage.
