This report covers the present scenario and the growth prospects of the winter tire market in Belgium for the period 2015–2019. Forecasts and analysis of the market have been done in terms of volume. The market size is calculated based on the unit sales of winter tires in Belgium.

Tires track their history back to the mid-1800s when solid tires were more prevalent. With time and new advances, solid tires were replaced by pneumatic tires, which were first used on automobiles by the Michelin brothers, who went on to become one of the prominent tire vendors in Europe.Over time, the tire market has witnessed new technology breakthroughs and the entry of many vendors.

Agricultural films are new-age films that are a component of modern farming technologies used to increase farm productivity. They are generally made from a variety of plastic resins such as different grades of PE, EVA, PVC, and PVOH. They offer a wide range of benefits in mulching, silage, and greenhouse applications such as soil temperature and moisture control, elimination of weeds, enabling lesser use of herbicides, storage and growth of crops in greenhouses, and prevention of soil erosion, in addition to protecting cattle fodder in silage bales. But, owing to disposal and pollution hazards, they are facing competition from non-biodegradable alternatives. The key customers of agricultural films are crop growers, processors, and retail packagers, who are the major stakeholders across the agricultural and horticultural sectors.

将笼型八聚倍半硅氧烷(POSS)与对-甲苯基缩水甘油醚 (TGE)反应,合成了顶角含有苯环的笼形八聚倍半硅氧烷无机/有机纳米杂化物(PTGE),将该杂化物添加到双酚A型环氧树脂(E44)中对其改性,测定固化后改性环氧树脂复合材料的力学性能和热稳定性能。结果表明,改性后环氧树脂的冲击强度、拉伸强度和断裂伸长率较改性前有了明显的提高,热稳定性大大增强。

采用反相悬浮法制备聚乙烯醇(PVA)/羧甲基纤维素钠 (CMC-Na)交联微球。通过正交法探讨了戊二醛用量、原料配比、催化剂用量以及反应温度对产率和平衡溶胀率的影响;采用红外光谱、扫描电镜对微球的化学组成和表面形貌进行分析,并研究了微球在不同pH条件下的溶胀行为。正交试验结果表明,最优实验方案下微球产率达到88.89%。红外光谱和扫描电镜测试结果表明,反应生成了PVA/CMC微球,微球球形度和分散性优良,粒径分布均匀,微球平均粒径为195μm。溶胀性能研究表明,在酸性环境中微球先溶胀后退溶胀;在碱性环境中微球不断溶胀直到溶胀平衡,且在碱性环境中微球的平衡溶胀率1.75远大于在酸性环境中的平衡溶胀率0.89,微球表现出pH敏感性。根据微球的pH敏感性,有望作为结肠靶向药物载体材料。

环烯烃共聚物(COC)材料具有比聚甲基丙烯酸甲酯 (PMMA)更加优良的光学性能、尺寸稳定性与极低的吸水性。以具有微结构的塑件——微流控芯片为研究对象,利用单因素和正交试验研究COC材料注塑成型过程工艺参数对微结构复制度的影响规律并加以分析。结果表明:熔体温度对其微通道的复制度影响最大,是影响微通道复制不完全的主要因素;注射压力和模具温度次之;保压压力和注射速度的影响较小。
