Pasta-making machine conditioning polymer clay. Bakelite, an early plastic, was popular with designers and was an early form of polymer clay, but the phenol base of uncured Bakelite was flammable and was eventually discontinued. Polymer clays were first formulated as a possible replacement for Bakelite.
A block of Sculpey Figurines made of Sculpey. Sculpey (often misspelled as Sculpy) is the brand name for a type of polymer clay that can be modeled and put into a conventional oven to harden, as opposed to typical modeling clays, which require a much hotter oven, such as a kiln. Until it is baked, Sculpey has a consistency somewhat like Plasticine.
FIMO was first a plastic modeling compound brought to the attention of German dollmaker Käthe Kruse in 1939 as a possible replacement for plastic compounds. It was not suitable for her doll factory use, and she turned it over to her daughter Sophie Rehbinder-Kruse, [3] who was known in the family as "Fifi" (hence FIMO, from Fifi's Modeling Compound).
Polymer clay is a modelling material that cures when heated from 129 to 135 °C (265 to 275 °F) for 15 minutes per 6 millimetres (1 ⁄ 4 in) of thickness, and does not significantly shrink or change shape during the process. Despite being called "clay", it generally contains no clay minerals.
The presence of water plays a crucial role in the mechanical behavior of natural fibers. Hydrated biopolymers generally have enhanced ductility and toughness. Water plays the role of a plasticizer, a small molecule easing passage of polymer chains and in doing so increasing ductility and toughness. When using natural fibers in applications ...
Inventor of air conditioning and founder of the Sirocco Engineering Works in Belfast Sir Samuel Cleland Davidson , KBE (18 November 1846 – 18 August 1921) was a British inventor and engineer. Through his career in the tea import business he invented and patented a number of industrial machines and developed the earliest air conditioning systems.
