Talc reinforcement of polylactide and biodegradable polyester blends via injection‐molding and pilot‐scale film extrusion

Journal of Applied Polymer Science, 2021
As a renewable and biodegradable polymer, polylactide (PLA) has taken a foothold in the packaging industry. However, the thermomechanical and barrier properties of PLA-based films need to be improved to facilitate a wider adoption.

Pulmonary talcosis in the setting of cosmetic talcum powder use

Respiratory Medicine Case Reports, 2021
Pulmonary talcosis is a rare pneumoconiosis that is difficult to diagnose and may progress to debilitating lung disease. Four types of talcosis are described in literature: talc-silicosis and talc-asbestosis secondary to inhalation in industry workers ...

A Review of the Talc Industry’s Influence on Federal Regulation and Scientific Standards for Asbestos in Talc

New solutions : a journal of environmental and occupational health policy : NS, 2021
The talc industry and Food and Drug Administration (FDA) have asserted that talc has been asbestos-free since 1976 when the industry created a voluntary specification for the asbestos content of cosmetic talc.

An investigation into the tensile properties of recycled high-density polyethylene (rHDPE) blended with talc filler

Results in Materials, 2023
High-density polyethylene (HDPE) is a well-established thermoplastic; however, with concerns about the fate of plastics at end-of-life, there is a growing interest in strategies to utilize recycled HDPE (rHDPE) in place of virgin HDPE (vHDPE). This study

Properties of 3D Printable Poly(lactic acid)/Poly(butylene adipate-co-terephthalate) Blends and Nano Talc Composites

, 2020
Biodegradable poly(lactic acid) (PLA) filaments have been widely used in the fused deposition modeling (FDM) 3D printing technology. However, PLA has low toughness and low thermal resistance that affects printability and restricts its industrial ...

Effects of talc particle size on the non-isothermal crystallization kinetics and activation energy of isotactic polypropylene-based composites

eXPRESS Polymer Letters
This study investigates the non-isothermal crystallization behavior of isotactic polypropylene (iPP) reinforced with two types of talc fillers: micrometric talc (μ-talc) and standard talc (S-talc).

Semi‐Brittle Deformation of Talc at the Base of the Seismogenic Zone

Geophysical Research Letters, 2023
Talc is commonly found in the cores of exhumed faults and may be important to the dynamics of slip in active fault zones. To understand the rheology of talc at conditions relevant to subduction zones, we conducted torsional deformation experiments at ...

Melt crystallization of PLA/Talc in fused filament fabrication

Materials & Design (1980-2015), 2019
The fused filament fabrication (FFF) process is characterized by fast local temperature decrease. Such characteristic usually leads to lower crystallinity degree in final printed parts when semi-crystalline polymers are used.
