Summary
Industrial hempseed oil shows promise as a sustainable rubber compounding alternative. This eco-friendly extender oil reduces rubber hardness and mixing energy, offering a greener solution to petroleum-based oils.
Area of Science:
- Materials Science
- Sustainable Chemistry
- Polymer Engineering
Background:
- Growing regulatory pressure on polycyclic aromatic hydrocarbons (PAH) necessitates alternatives to petroleum-based extender oils in rubber compounding.
- Industrial hempseed oil presents a potential sustainable and eco-friendly option for rubber formulations.
- Evaluating vegetable oils alongside petroleum-based oils is crucial for identifying viable replacements.
Purpose of the Study:
- To investigate the viability of industrial hempseed oil as a sustainable extender oil in rubber compounding.
- To analyze the physical and mechanical properties of rubber composites incorporating industrial hempseed oil.
- To compare the performance of industrial hempseed oil with various vegetable and petroleum-based oils.
Main Methods:
- Utilized automated neural networks for analyzing rubber composite properties.
- Compared rubber compounds with varying concentrations (0-30 phr) of industrial hempseed oil, six vegetable oils, and three petroleum-based oils.
- Performed sensitivity analysis to identify key factors influencing rubber hardness.
Main Results:
- Compounds with 20 phr of industrial hempseed oil and raw soybean oil achieved the highest cure rate index (64.32 1/min).
- Industrial hempseed oil reduced rubber hardness by 18% compared to conventional oils, reaching 40.5 Shore A at 30 phr.
- Mixing energy consumption decreased by up to 12% for vegetable oil samples versus mineral oils.
- Neural network predictions for cure rate index, hardness, and power consumption exceeded 99.2% validation performance.
Conclusions:
- Industrial hempseed oil is a viable and effective eco-friendly substitute for conventional mineral oils in rubber compounding.
- The use of industrial hempseed oil contributes to enhanced processing efficiency and reduced energy consumption.
- This research supports the adoption of sustainable materials in the rubber industry, aligning with environmental regulations.

2.5K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.

01:31Plasticizers
326
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

02:35Free-Radical Chain Reaction and Polymerization of Alkenes
9.3K
The conversion of alkenes to macromolecules called polymers is a reaction of high commercial importance. The structure of the polymer is defined by a repeating unit, while the terminal groups are considered insignificant. The average degree of polymerization represents the number of repeating units in the polymer molecule and is denoted by the subscript n.

3.9K
Ziegler–Natta polymerization is another form of addition or chain‐growth polymerization used for synthesizing linear polymers over branched polymers. The catalyst used for polymerization is the Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, who developed it in 1953. This catalyst is an organometallic complex of titanium tetrachloride and triethyl aluminum, with the active form of the catalyst being an alkyl titanium compound. Using the Ziegler–Natta...

01:20Radical Autoxidation
3.0K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

01:21Green Algae
694
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...
