BRB Introduces Silane for Improved Adhesion and Coupling

BRB International introduces BRB Silanil® 505, a silane with bifunctional properties. Silanes are becoming increasingly complex and versatile in their applications due to their bifunctionality.

BRB Silanil® 505 is an example of this. With two amino groups in its structure, it could serve as an adhesion promoter, and the three ethoxy groups give it coupling agent properties. Due to the ethoxy groups, BRB Silanil® 505 will release ethanol when it autocatalytically hydrolyzes in the presence of moisture.

Enhancing Adhesion to Metal and Glass:

BRB Silanil® 505 can be used in mineral-filled composites to improve mechanical properties and has also proven to be an additive for foundry resins. As an adhesion promoter, due to the presence of two amino groups, it is an additive for improving adhesion to inorganic substrates such as metal or glass.

The bifunctionality is what makes it possible to bind both inorganic and organic polymers by forming a molecular bridge between the two substrates. BRB Silanil® 505 will react as a strong base due to the two amino groups in its structure.

This innovative material is used in a wide range of lightweight, shock-absorbing applications, such as cushioning materials for home electric appliances, transportation containers for fresh food, and materials used in the automotive and transport industries. The foam particles can be processed with existing molding equipment, and their characteristics are similar to those of polyolefin foams.

The microplastic-free recognition of Kaneka’s Green Planet™ Expanded Beads follows a comprehensive assessment conducted by Normec OWS, an external verification laboratory. During the verification process, the product's aqueous aerobic biodegradability was evaluated based on CO2 evolution. The results indicated that the material achieves a mineralization level of +60% over a period of 28 days according to OECD test method 301 B. These results confirm that the product fully degrades without leaving any synthetic residues, reinforcing its role as a sustainable alternative in the foam applications industry and contributing to the fight against microplastic pollution.

"We are proud that Kaneka Green Planet™ Expanded Beads L40N have been officially recognized as microplastic-free in line with the highest environmental standards set by EU Regulation 2023/2055. This milestone reflects our dedication to protecting the planet and delivering eco-friendly particle foam solutions without compromising performance and quality. It will enable us to engage further with brand owners, molders, and consumers, and help us work towards a microplastic-free foam industry," said Luc Point, General Manager of Foam & Residential Techs EMEA for Kaneka Belgium.

Today's KNOWLEDGE Share : IZOD OR CHARPY NOTCHED IMPACT TEST

Today's KNOWLEDGE Share

During one of my recent BIMS-1 sessions I was asked to comment about surprising results obtained on notched Charpy tests when using “molded-in notches” vs. post-molding machined notches.

1. First of all molded pre-notched bars should be accurately measured since the effective notch radius will likely be somewhat smoothed out by the material shrinkage and warpage. If effective radius is larger, that will already shift the performance to an apparent better impact

2. Machined notches will typically create some damage on the machined surfaces which might further help initiating the brittle failures that we typically want to see in notched samples. This will likely reduce the apparent performance since crack initiation energy is essentially absent due to the machining pre-damage

3.The single most important reason for the discrepancies however is the fact that machining a molded sample means biting through the frozen skin and the outer layers created by the highest shear stresses:

4. In amorphous materials (where the discrepancy should be a bit less severe) the tip of the notch will be located in deeper layers showing a bit more “physical aging” from the process (lower cooling rate).

5. In semi-crystalline grades the discrepancies can be dramatic since one would typically find the machined notch tip located well below the unique morphology of the frozen skin. As a reminder, the frozen skin typically has a totally different mechanical response due to morphology and orientations

Never forget that notched IZOD or CHARPY are not “material properties” but just the quantitative output of a normalized test intrinsically sensitive to any sample or test variation.

Today's KNOWLEDGE Share : Perpetuus Launches Environmental Graphene Masterbatch for Tire Industry:

Today's KNOWLEDGE Share

Perpetuus Advanced Materials introduces the first in its range of proprietary nano engineered graphene-enhanced masterbatch compounds, initially formulated specifically for the field of commercial, passenger and industrial tire manufacturing sectors. The initial offering will be broadened to include other polymer/elastomer masterbatches suitable for industries such as hoses, seals, gaskets, V-belts, conveyor belts, etc.

Using its environmentally friendly, plasma treatment process, Perpetuus graphenes are integrated into the masterbatch. The resultant masterbatch is now available in industrial quantities, allowing tire manufacturers to integrate this breakthrough material into their existing production processes.

Perpetuus’s unique graphene manufacturing process is environmentally safe by avoiding traditional wet acid, solvent, or surfactant treatments, eliminating the need for energy-intensive drying steps and the associated disposal of post-production toxic waste. Instead, the dry plasma process conserves energy, supports sustainable industrial scale production and aligns with the company’s commitment to environmentally responsible manufacturing.

Perpetuus’s graphene masterbatch formulation combines its surface-engineered, plasma-treated graphenes with natural rubber carbon black and other industry known functional fillers, creating an innovative base material for tire and other rubber product manufacturing.

Integrating Perpetuus’s graphene masterbatch into tire tread formulations yields significant performance gains, with road testing showing up to a 40% reduction in tire tread wear, together with improved overall handling and braking, particularly in the wet. The enhanced dispersion and bonding of ingredients in the masterbatch also reduces PM2.5 tire wear particles released during road abrasion. A major step forward in reducing harmful particulates that contribute to air pollution.John Buckland, CEO of Perpetuus Advanced Materials said: “In the 20 years since graphene was discovered, almost every use for the material has been developed in laboratories around the world, however the lack of affordable high quality graphenes has prevented known commercial applications coming to market. Our plasma treated surface engineered graphenes solve this problem which are now available in commercial quantities to all sectors of industry.”

This innovation aligns with key regulatory goals, including the UK’s Clean Air Act 2022 and the EU Clean Air Policy, which secure citizens’ rights to clean air. Moreover, reducing tire-derived particles and chemicals in roadway runoff has potential benefits for aquatic ecosystems and improving water quality of urban drainage systems.
