N‑Butylbenzene sulfonamide ( #BBSA , CAS 3622‑84‑2) is widely used as a plasticizer in #polyamide (PA) materials, where it supports durability and improved flexibility. BBSA is commonly incorporated into #coatings , #adhesives , and molded PA components for a variety of industrial applications. As regulatory expectations continue to evolve, material selection is increasingly influenced by health, safety, and environmental considerations. According to the #EuropeanChemicalsAgency (ECHA), BBSA may cause organ damage through prolonged or repeated exposure and is classified as harmful to aquatic life with long‑lasting effects. These classifications require specific hazard statements to be included on Material Safety Data Sheets. In response, Emery Oleochemicals—drawing on its long history as a supplier of safe, naturally derived chemicals—is developing an alternative #plasticizer designed to replace BBSA. This next‑generation solution features 100% biobased carbon content and requires n...

Yet in recycled PET (rPET), IV loss is a common and often misunderstood issue. So why does IV tend to decrease during recycling? 1.Thermal degradation during reprocessing: PET is sensitive to heat. During extrusion and re-melting, excessive temperature or long residence time can cause polymer chain scission, directly reducing molecular weight and therefore IV. 2.Hydrolysis caused by residual moisture: Even small amounts of moisture can trigger hydrolytic degradation at high processing temperatures. Without proper drying control, IV loss can occur rapidly and irreversibly. 3.Mechanical stress in multiple processing steps: Grinding, washing, extrusion, and filtration all introduce mechanical shear. Each step slightly shortens polymer chains, and the cumulative effe...

Evonik has strengthened its epoxy curing agent offering for the Americas region to address challenging application conditions with Ancamine® 2868 and Ancamine® 2844. Both solutions are designed to support epoxy formulators in protective, marine, and industrial coatings requiring rapid cure, productivity, and reliable performance under demanding temperature and humidity conditions. Ancamine® 2868 is a modified cyclic polyamine designed to function as a highly efficient, crosslinkable accelerator for epoxy systems. When used as a co‑curing agent with polyamides, #amidoamines , and #cycloaliphaticamine curing agents, it enables rapid thin‑film cure while maintaining key physical and barrier properties, surface appearance, and corrosion protection. By significantly accelerating cure speed, Ancamine® 2868 allows epoxy formulators to fine‑tune performance and formulation response, while supporting efficient processing and broad formulation flexibility. These attributes make it well suited f...

It has completed mass production technology and product reliability evaluations for the new offering, whose helps improve lower-biofouling performance of reverse osmosis (RO) membrane and stabilizes long-term operations. This module is based on a high-removal UF #membrane that the company unveiled in February 2025. Nations everywhere are tightening wastewater regulations as water demand rises. Regions with limited resources position reusing wastewater as vital for supply stability. The challenge is that wastewater contains a lot of #biopolymers that are a k...

PLAST was established in 1964 in the course of the European Plastics Congress and is now one of Europe’s longest-standing and most important plastics trade fairs. It captures the attention of the entire industry in the years it takes place, not least because it is held every three years. Strong presence in a key European market KRAIBURG TPE’s long-standing presence at the trade fair reflects its close cooperation with Italian customers. Italy is after Germany the company’s second-largest market in Europe. A comprehensive service network ensures proximity to customers across various regions and industry segments, especially the automotive industry. Focus on an overall presentation of KRAIBURG TPE The long interval between the PLAST editions means that exhibiting companies focus on both current developments and the most comprehensive possible presentation of their product and service portfolios during the four days of the trade fair (June 9 to 12, 2026). Luca Triglia, Sales Manager Italy...

BASF today announced the launch of Reduced Product Carbon Footprint (ReducedPCF) #Elastollan®ThermoplasticPolyurethane (TPU) portfolio in Asia Pacific, enabling customers to lower the carbon footprint of their products while maintaining the proven performance of Elastollan. The ReducedPCF grades are achieved through active PCF reduction measures, including the use of lower‑emission utilities and fossil feedstocks with lower PCF. The Product Carbon Footprint calculation methodology follows TfS (Together for Sustainability) Guideline requirements and ISO 14067. Through these active measures, the new ReducedPCF grades achieve a PCF reduction of 10-30% compared to the PCF of current Elastollan grades, while remaining technically identical. Selected Elastollan TPU products manufactured at the site in Shanghai may additionally incorporate site‑specific mass‑balance biomethane as an active PCF reduction measure. The Elastollan ReducedPCF portfolio will be produced at BASF’s site in Shanghai,...
