Poly-Foam 2026; Suzhou, Oct. 13-15
Foam Update will host the tenth International Foam Conference on Oct. 13-15 at the Shangri-la Hotel in Suzhou. The conference operation is being assisted by the Inter Foam group. The theme is ‘Specialty Foam,’ highlighting the diversified performance requirements for foam in a wide variety of businesses in an ever-demanding market. It can be imagined that the function groups in the specialty polymer could increase its material strength and/or foaming capability via the bonding and debonding of the chemical or physical connections to simply offer another dimension over the crystallinity and branching structure of the conventional thermoplastic materials. It will surely make the knowledge-technology-business cycle more fascinating than before. The attached illustration shows the near final program for the auditorium on Oct. 13 which is designed to help the practitioners in solving problems in daily operation, and the conference program for Oct. 14-15. Registration information is also attached. Electronic versions of power point (PPT) from the presenters will be provided bilingually, in Chinese and English—to be distributed at conference check in. For attendees who need interpretation, the use of an interpreting tool such as ChatGPT is highly recommended to help them make the most of the presentations. An exhibition will also be set up to encourage more focused discussions and interactions between exhibitors and attendees.
It is anticipated that this gathering is a valuable opportunity for the creative young blood and the seasoned experts to come together, exchange ideas, and facilitate the transfer of the torch, making the foam platform more fruitful into the future. New business is always a driving force to push the platform forward. Understanding how innovation is formed is more critical than ever in the investment of new technology. Yet it is always a plus in renewing friendship and picking up new knowledge and skill set in this unique event. We are looking forward to seeing our fellow experts in foam and emerging stars at this conference.

About Poly-Foam 2026 Foam Update is planning to host the 10th Global Poly-Foam Conference Oct. 13-15, 2026 at Suzhou. Its theme is Specialty Foam. Oct. 13 is dedicated to the Expert Auditorium, which is for on-the-job training from well-known experts, 14-15 for technical presentations from well-known speakers. An exhibition area will be established to strengthen the knowledge-manufacturing-business cycle. Both conventional foam markets and innovations; such as automotive, construction, packaging, insulation, footwear, semiconductors, medical, and health care, are welcome. In the last three decades there has been no major breakthrough in foaming technology; yet social awareness and quest for innovation continue to increase, especially nowadays, business is driving manufacturing more than before. How to meet or exceed customers’ expectations in a timely manner and how to renew the foaming technical skill set become critical. Moreover, the specialty polymer provides chemical groups that the conventional polymers (i.e. PE, PP, and PS) could not. The chemical groups can interact with blowing agents to create novel performances for advanced applications to a higher level. However, the chemical group may cause adverse effects in manufacturing. This development process could be more complex, yet more rewarding. It is our hope to get together quality scientific and technical staff from industry, research institutes, and college together in the conference to constructive interactions to generate ideas to improve processing efficiency and product quality. They can not only make manufacturing and R&D more robust but also make new products’ delivery more profitable. |

| Abstract: | ||
 The invention relates to a foaming process using carbon dioxide solution, comprising: put a parison into the carbon dioxide solution for primary foaming, remove and put the parison into the carbon dioxide solution for secondary foaming to get the foam product. Compared with foaming process using high-pressure gas directly, the foaming process using polar liquid system can get a uniform foam structure with high foaming rate faster, and has good foaming effect for high crystalline polymers. To control the change of temperature and pressure after the introduction of carbon dioxide, the impact and penetration of carbon dioxide on the surface of the crosslinked material can be controlled first, and the solubility of carbon dioxide in the polar system can be improved by further increasing pressure and temperature, thereby promoting the formation of uniform foam structure with high foaming rate in the subsequent heat foaming process. |

 An expandable downhole device may be used for supporting a wellbore and as a flow/sand control device. The expandable downhole device is initially RIH in a compressed state. Once the expandable downhole device reaches a predetermined depth in the wellbore, the expandable downhole device is transitioned from the compressed state to an expanded state to support the wellbore from collapsing. In the expanded state, an activation chamber of the expandable downhole device is expanded from a collapsed state to press an outer shroud of the expandable downhole device against the wellbore. A shape memory foam of the expandable downhole device is also expanded and hardens in the expanded state. The shape memory foam acts as a support layer for the activation chamber to provide additional support for the wellbore. The shape memory foam may be a porous material to be a filter media of the expandable downhole device. |

| Abstract: | ||
 Techniques and materials provide for thermal insulation for tanks, such as tanks for use in space flight missions. Microporous glass blocks may be used as an insulative bridge between spray-on foam insulation and a stainless steel wall of a tank, for example. Blocks of microporous glass may be mechanically attached to the interior of the tank, after which spray-on foam insulation is applied directly to the blocks. The bridging insulation provided by the microporous glass blocks allows the temperature of the stainless steel tank wall to exceed the usable temperature of the spray-on foam insulation by preventing a substantial portion of heat of the stainless steel wall from reaching the spray-on foam insulation. An insulated tank may instead comprise a tank wall that is a sandwich-structured composite layer including an exterior skin, an interior skin, and a core that presents a relatively long thermal path, for improved thermal insulation. |
