Commercial nitrile gloves, unfilled nitrile films and biomaterial-filled films were subjected to accelerated heat ageing from 50 to 80 °C, and tensile strength retention was used to characterise degradation. Activation energies and shelf-life predictions at 30 °C were estimated using the Arrhenius formalism, enabling a comparative kinetic assessment of the different formulations. The mathematical analysis revealed apparent differences in degradation kinetics: collagen-filled films exhibited the highest activation energy of 110.9 kJ/mol and the longest predicted shelf life of 6.1 years, reflecting improved interfacial compatibility and a more uniform microstructure that enhanced thermo-oxidative resistance. Kenaf-filled films exhibited a lower activation energy of 103.5 kJ/mol and the shortest shelf life of 2.3 years, consistent with weaker matrix adhesion and reduced dispersion. Commercial gloves and unfilled films exhibited comparable activation energies, approximately 105.5 kJ/mol and 103.4 kJ/mol, respectively, and predicted shelf lives of approximately 2.8 years. These kinetic parameters were consistent with thermogravimetric and microscopic observations, thereby validating the mathematically derived trends: greater thermal stability in protein-filled films and faster structural breakdown in kenaf-filled films. Overall, this work demonstrates how the Arrhenius-based kinetic analysis provides a framework for interpreting ageing behaviour in nitrile films incorporated with biomaterials. The results highlight the significance of biomaterial–matrix interactions in engineering nitrile-based materials with tailored durability or degradability, providing a foundation for designing more sustainable nitrile-dipped products.</p></div>","PeriodicalId":662,"journal":{"name":"Journal of Rubber Research","volume":"29 3","pages":"601 - 614"},"PeriodicalIF":1.4,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148859831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using national household-level data collected from a stratified random sample of 1552 households between 2012 and 2014, and applying propensity score matching, the findings indicate that rubber crop diversity has a statistically significant positive effect on food expenditure, increasing annual per capita food expenditure by 1362–1418 baht. Additionally, rubber crop diversity promotes self-produced food consumption by 399–506 baht per person annually, thereby enhancing dietary resilience and food security for farmers.

We conducted large-scale randomised field trials in Ivory Coast comparing the performance of two commercially significant clones, RRIM600 and PB235, over five and six years of tapping, respectively. While RRIM600 demonstrated superior vegetative vigour (girth and conicity) with juvenile methods, the cumulative rubber yield over 5 years did not differ significantly from MB. In contrast, the high-yielding clone PB235 demonstrated a statistically significant advantage: JC yielded 15% more than MB, and IV (7%) and JB (5%) also showed a better performance and greater yield stability in subsequent tapping years. The enhanced trunk conicity observed in juvenile materials promises a significant advantage as tapping moves to lower trunk positions in later years. For large-scale deployment, the JB method, which uses budwood from in vitro rejuvenated plants grafted onto seedling rootstock, appears to be the most promising.

This study employs a mixed-methods empirical approach to examine the key factors that limit productivity and value chain development in Nigeria’s rubber industry, and to identify evidence-based policy pathways for sector revitalisation. Primary data were collected from 200 smallholder rubber farmers across five major producing states and 30 industry stakeholders, complemented by secondary literature. Quantitative analysis, including regression modelling, was used to identify determinants of rubber productivity, measured as latex output per hectare per year, while qualitative interviews provided institutional and market-level insights. Results indicate that ageing plantations, limited access to credit, weak extension services, and climate variability are the most significant constraints affecting smallholder productivity. Regression results show that access to credit, adoption of high-yielding clones, extension services, and climate-resilient practices are all statistically significant predictors of productivity. Stakeholder perspectives further highlight systemic bottlenecks, including inadequate processing capacity, weak market linkages, and the absence of a coherent national rubber development framework. The study concludes that Nigeria’s rubber sector is constrained not by agro-ecological limitations but by coordination failures across biological rehabilitation, finance, knowledge systems, and institutional governance. Scenario-based analysis suggests that under coordinated policy reform and targeted investment, Nigeria could substantially expand its participation in global natural rubber markets over the medium- to long-term.
