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.

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.

A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.

A composite film having a high dielectric permittivity engineered particles dispersed in a high breakdown strength polymer material to achieve high energy density.

The invention relates to a PET regranulate which, after modification of a granulated PET recyclate, has an intrinsic viscosity of at least 0.95 dl/g measured according to ASTM D 4603, preferably greater than 1.0 dl/g and particularly preferably between 1.1 dl/g and 1.7 dl/g and is suitable for the production of extrusion blow-molded containers.

This invention covers injection stretch blow molded articles prepared from polyethylene resin having a bimodal molecular weight distribution (MWD), defined by the ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn), of from 2 to 20, comprising two polyethylene fractions A and B, fraction A being substantially free of comonomer and having a lower weight average molecular weight and a higher density than fraction B, each fraction prepared in different reactors of two reactors connected in series in the presence of a metallocene-containing catalyst system.

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.

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.

The invention relates to a device and a method for semi-continuous blow moulding of fiber-reinforced, thermoplastic, endless, hollow-profile-shaped components with longitudinally constant or varying cross-sections, consisting of at least one consolidation tool, which, in its closed state, encloses a preform enclosing an elastically moldable pressure chamber.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.
