Chemplast Sanmar Ltd expects to commission its Paste PVC expansion project by the fourth quarter of the current financial year, the company said on Tuesday. The city-based specialty chemicals company has recorded a consolidated net loss of Rs 89.38 crore, during the October-December 2023 quarter. The consolidated profit after tax for the corresponding quarter of last financial year stood at Rs 27.14 crore, the company part of the SHL Chemicals group, said in a statement. “After a relatively better second quarter, Q3 FY24 performance ran into heavy weather due to further correction in PVC prices on account of dumping from China and other countries, slow down in other chemicals (Caustic Soda, Chloromethanes) business due to the over-supply situation in India, increase in key feedstock, prices and adverse impact of the lag effect in correction of VCM prices,” company MD Ramkumar Shankar said. For the nine months ending December 31, 2023, the consolidated net loss was at Rs 127...

Q disadvantages of cellulosic fibers
RachelSinclair
Cedric Release Time: June 19, 2024, 3:11 AM
Cellulosic manufactured fibers, derived from plant materials, have several disadvantages impacting their application and environmental footprint. Firstly, they can exhibit lower strength, especially when wet, making them less durable compared to synthetic fibers like polyester. This limits their use in applications requiring long-lasting materials. Additionally, the production process of some cellulosic fibers involves chemical treatments that can release harmful pollutants unless carefully managed. For instance, viscose production, a common cellulosic fiber, uses carbon disulfide, which poses environmental and health risks. Furthermore, while cellulosic fibers are praised for their biodegradability, the chemical residues from their production can negate this benefit if not properly treated. Lastly, compared to more established fibers, cellulosic manufactured fibers often have limited variety and availability, which may restrict design options and increase costs for manufacturers and c...

JeanGladstone Release Time: June 1, 2024, 9:34 AM
Polypropylene, a thermoplastic polymer, is noted for its versatility and durability, making it a popular choice in various industries, ranging from packaging and textiles to automotive components and medical devices. It is derived from the polymerization of propylene gas, a process that gives it unique properties such as resistance to chemicals, heat, and fatigue, along with being lightweight and having a high melting point. Polypropylene can be easily molded and has become indispensable in everyday items due to its ability to be recycled, further contributing to its value in sustainable manufacturing practices.

Q what are 4 benefits of eating fiber

Insoluble fiber is a type of dietary fiber that does not dissolve in water. Found in foods like whole grains, nuts, vegetables, and wheat bran, it helps promote regular bowel movements and prevent constipation by adding bulk to the stool. Unlike soluble fiber, which forms a gel-like substance in the gut and can help lower cholesterol and blood glucose levels, insoluble fiber stays relatively intact through the digestive system. This characteristic aids in speeding up the passage of food and waste, contributing to a healthy digestive tract. Incorporating insoluble fiber into one’s diet is beneficial for digestive health and can be part of a balanced diet to maintain or improve overall health. It’s important to increase fiber intake gradually to allow the body to adjust, and to consume plenty of water.

Q polypropylene price per ton
RachelSinclair
FloraJob Release Time: May 30, 2024, 6:47 AM
The price of polypropylene per ton can vary widely depending on factors like global oil prices, production costs, and market demand. As of the last update in 2023, prices were hovering around $900 to $1200 per ton, but these figures can fluctuate. It’s important to note that regional differences can also significantly impact prices, with costs in areas with higher production capacity generally being lower. For accurate pricing, it’s advisable to check the latest market reports or contact suppliers directly, as they can offer real-time quotes and might provide volume discounts or have additional fees that affect the final cost.

Q flammability properties of polypropylene
RachelSinclair
KirkDelia Release Time: May 7, 2024, 11:45 AM
Polypropylene, a thermoplastic polymer used in a wide variety of applications, exhibits moderate flammability characteristics. It ignites at a temperature of approximately 570°F (300°C) and burns with a bright, clean flame while melting. Unlike some other plastics, polypropylene does not drip excessively while burning, which can limit the spread of flames. However, it releases a variety of combustion gases, including carbon monoxide and carbon dioxide. Its flammability can be reduced through the incorporation of flame retardants, making it safer for use in applications where fire resistance is crucial. Nevertheless, ensuring proper safety measures and compliance with fire safety standards is essential when using polypropylene in environments with high fire risk.

Q how do you spell yarn
RachelSinclair
MariaBernard Release Time: May 1, 2024, 3:01 PM
The term “shein” is not widely recognized in the context of yarn or fiber arts. It’s possible that there might be a misunderstanding or misspelling of the term you’re looking for. If you’re referring to a “skein” of yarn, that’s different and quite relevant in knitting, crocheting, and weaving. A skein is a unit of yarn that’s been loosely coiled and is often how yarn is sold in stores. It varies in weight and length depending on the type of yarn. For those involved in fiber arts, understanding how to work with skeins—such as how to start a skein or how to prevent it from tangling—is crucial. If “shein” pertains to something specific within the realm of textiles that’s less known or a brand-related query, additional context might help clarify the question. Nonetheless, the importance of correct terminology in textile arts cannot be understated, as it helps in ensuring clear communication and understanding among ent...

Q yarn maven

JohnZechariah Release Time: May 1, 2024, 2:23 PM
Yarn, a long continuous length of interlocked fibers, is essential in knitting, weaving, crocheting, and sewing. It goes by various names depending on its material, usage, or regional terminology. Some common alternatives include thread, particularly when referring to finer yarn used for sewing, embroidery, or crochet. Wool is often used interchangeably with yarn, especially in regions where sheep’s wool is the primary fiber. However, this can be misleading as yarn can be made from a myriad of materials beyond wool, such as cotton, acrylic, and silk. In the crafting community, terms like “fiber” are also used, emphasizing the raw material aspect. “Strand” might be used when focusing on the structure or when several yarns are twisted together. While “yarn” is the universally accepted term, these alternatives reflect the diversity and richness of the textile world.
