Melt strength of linear low‐density polyethylene/low‐density polyethylene blends

Journal of Applied Polymer Science, 2002
AbstractLinear low‐density polyethylenes and low‐density polyethylenes of various compositions were melt‐blended with a batch mixer. The blends were characterized by their melt strengths and other rheological properties. A simple method for measuring melt strength is presented.

Crystallization of low-density polyethylene- and linear low-density polyethylene-rich blends

Journal of Applied Polymer Science, 2000
The crystallization of a series of low-density polyethylene (LDPE)- and linear low-density polyethylene (LLDPE)-rich blends was examined using differential scanning calorimetry (DSC). DSC analysis after continuous slow cooling showed a broadening of the LLDPE melt peak and subsequent increase in the area of a second lower-temperature peak with ...

Polyethylene, Low-density

2009
Abstract Introduction LDPE is produced under high pressure (82–276 MPa) and high temperature (405–605 K) with a free radical initiator (such as peroxides and oxygen) and contains some long chain branches (LCB), which could be as long as chain backbones, and short chain branches (SCB).(3) It is produced by either a tubular or a stirred ...

Photo-oxidation of blends of low density polyethylene and linear low density polyethylene

Polymer Degradation and Stability, 1985
Abstract Films of blends of low density polyethylene with linear low density polyethylene and of the pure polymers were photo-oxidised for different times. From mechanical measurements the rate of photo-oxidation seems greater for the linear low density polyethylene and its rich blends.

Correlation of structure, rheological, thermal, mechanical, and optical properties in Low Density Polyethylene/Linear Low Density Polyethylene blends in the presence of recycled Low Density Polyethylene and Linear Low Density Polyethylene

Polymer Engineering & Science
AbstractPost‐industrial low‐density and linear low‐density polyethylene blown films are mechanically recycled for reutilizing in the production of blown films for packaging applications. This process enables the production of films with lower cost and similar properties while preserving the environment and lowering the amount of waste material disposed

Elongation viscosity estimates of linear low‐density polyethylene/ low‐density polyethylene blends

Polymer Engineering & Science, 1992
AbstractThe elongational viscosity (EV) of two series of linear low‐density polyethylene/low‐density polyethylene blends was estimated using an entry flow analysis. The difference, t − n, between the power law index t of the elongational viscosity and the power law index n of the viscosity, is proportional to the LDPE content for both series of blends ...

Mechanical and Conductive Properties of Carbon Black-filled High-density Polyethylene, Low-density Polyethylene, and Linear Low-density Polyethylene

Journal of Thermoplastic Composite Materials, 2009
High conductive composites were manufactured using single screw extruder melt compound method with carbon black (CB)-filled high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). A low percolation threshold value was achieved from the composites consisting of 2 wt% CB (Printex) with HDPE ...

Study on ternary low density polyethylene/linear low density polyethylene/thermoplastic starch blend films

Carbohydrate Polymers, 2015
In this work, low-density polyethylene/linear low-density polyethylene/thermoplastic starch (LDPE/LLDPE/TPS) films are prepared with the aim of obtaining environmentally friendly materials containing high TPS content with required packaging properties.

Charge storage and transport in high density polyethylene and low density polyethylene

9th International Symposium on Electrets (ISE 9) Proceedings, 2002
High density polyethylene (HDPE) and low density polyethylene (LDPE) are widely used as dielectrics and insulating materials. In this paper, the influence of heat treatment during and after corona charging on charge storage stability and the transportation of detrapping charges in the bulk of HDPE and LDPE were investigated by isothermal surface ...

Elongational behavior of low density/linear low density polyethylenes

Polymer Engineering & Science, 1988
AbstractRheological data have been collected in isothermal elongational flow for three different types of blends, made from one low density polyethylene and three linear low density samples. In addition to the transient curves, elongation at break data are also reported.
