A configuration is adopted where the preform has a bottomed cylinder shape provided with a mouth portion and a body portion and, when molded by liquid blow molding into a container, the body portion is stretched in an axial direction at a stretch ratio of 1.50 or more and 3.10 or less and is stretched in a radial direction at a stretch ratio of 2.26 or more and 3.70 or less.

Propylene-based terpolymers for films

A terpolymer containing propylene, ethylene and an alpha olefins of formula CH2=CHZ wherein Z is an hydrocarbon group having from 2 to 10 carbon atoms wherein: (i) the content of ethylene derived units ranges from 0.5 wt % to 5.0 wt %; (ii) the content of alpha olefin derived units ranges from 1.0 wt % to 5.0 wt %; (iii) the area of the DSC curve after the peak of the melting point (Tm) represents more than 22%; of the total area of the DSC curve; (iv) the polydispersity index (PI) ranges from 2.0 to 7.0.

Article with visual effect

A blow molded article having a body portion that includes one or more walls surrounding an interior space. The one or more walls have an article inner surface, an article outer surface, and a wall thickness. At least a portion of the one or more walls includes one or more effect structures each having an effect surface normal having an orientation. Further there is a first region including a plurality of first effect structures having a first Average Normal Orientation, a second region including a plurality of second effect structures having a second Average Normal Orientation which is different from the first Average Normal Orientation, and a visual effect resulting from the difference between the first Average Normal Orientation of the effect structures in the first region and the second Average Normal Orientation of the effect structures in the second region.

Method and system for forming a self-sealing volume using a breather system

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

11254083 · 2022-02-22 · ·

Disclosed is a fluid transport pipe which has an inner layer, coming in contact with a fluid, comprising at least one aliphatic polyamide and at least one impact modifier and also at least one outer layer which is connected directly to the inner layer and is formed from an aliphatic polyamide and at least one flame retardant. While the inner layer ensures the chemical resistance relative to the fluids to be transported and the mechanical resistance, the flame resistance is ensured by the outer layer.

Heat resistant polyethylene terephthalate and a process for the preparation of the same

The present disclosure relates to a process for preparing polyester. The process for preparing the polyester essentially involves the preparation of the isosorbide oligomer and the isosorbide polymer from the isosorbide oligomer. The isosorbide oligomer or isosorbide polymer is then co-polymerized with the polyester. The copolymerization isosorbide oligomer or isosorbide polymer may be carried out at any stage of the preparation of the polyester. The polyester obtained in accordance with the process of the present disclosure can be used in packaging applications such as preparing packaging materials or containers. The material or container obtained from the polyester of the present disclosure is capable of withstanding a temperature of 60 to 90° C. without undergoing any deformation and shrinkage. Further, the material or container obtained from the polyester of the present disclosure is transparent or has lower color b* value.
