Natural bitumen pitch, from the tar pit above the McKittrick Oil Field, Kern County, California. Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt, while plant-derived pitch, a resin, is known as rosin in its solid ...
Carbon fiber is often time produced using two main methods: through the use of Polyacrylonitrile (PAN) and from pitch. [1] [2] [3] Pitch is a viscoelastic material that is composed of aromatic hydrocarbons. Pitch is produced via the distillation of carbon-based materials, such as plants, crude oil, and coal.
Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers. The primary components of rosin are diterpenoids , i.e., C 20 carboxylic acids .
Cutin is one of two waxy polymers that are the main components of the plant cuticle, which covers all aerial surfaces of plants, the other being cutan. It is an insoluble substance with waterproof quality. Cutin also harbors cuticular waxes, which assist in cuticle structure. [1]
Pinus rigida, the pitch pine, [2] [3] is a small-to-medium-sized pine. It is native to eastern North America , primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils.
Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs. Chemically, it consists of hydrophobic organic compounds, mainly straight-chain aliphatic hydrocarbons with or without a variety of substituted functional groups ...
The species are collectively known as sun pitchers, based on the mistaken notion that the heli of Heliamphora is from the Greek helios, meaning "sun". The name instead derives from the Greek helos , meaning "marsh", so a more accurate translation of their scientific name would be marsh pitcher plants . [ 2 ]
Mastic tears. Mastic (Greek: Μαστίχα) is a resin obtained from the mastic tree (Pistacia lentiscus). [1] It is also known as tears of Chios, [2] being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets.
